After you have successfully got an IP, please access the router by typing http://192.168.1.1 to configure the router. (If you have changed the route’s IP address, please type http://.) CHAPTER 3 CONFIGURING THE WIRELESS GATEWAY The first time you start to configure the gateway by the web using the web browser with address http://192.168.1.1, the gateway will ask you to login with the user name and password, both the user name and password are “admin” for the default value. Please change the User Name and Password from the default value to your own settings. Otherwise, the others might use the default value to enter your gateway easily. Please refer to 3.2.4 Advanced Setup >> Remote Management for more information. 3.1 Basic Configuration The basic configuration contains Internet Port, Local Port and the Wireless LAN configurations. After you finished the basic items, the gateway will work for most functions. 3.1.1 Internet Port The Internet Port connects to your modem to get the access to the Internet. You will need to configure for the right settings that is assigned by your ISP. DHCP Configuration The DHCP is the default service for the Internet Port; you will get the IP address from the ISP automatically. Host Name/Domain Name. Some cable ISPs require the host name and domain name as identification, Your may have to check with your ISP to see if your broadband Internet service has been configured with a host and domain name. In most cases, assign on your own or leave it as blank will work. Use Static DNS. If you want to use your own DNS instead of ISP’s provision, check this box, and give the IP address of the DNS in the field. (At least one in the primary field.) MAC address. Some ISPs allow you to connect to them with specified MAC address only, you can enter the MAC address manually or copy it from a PC which is attached to the Local Port, you just type in its IP address, the gateway will copy the MAC address from that PC. The gateway comes with the factory default MAC address, no need to change the default value if the ISP is not checking the MAC address of your Internet Port. PPPoE Configuration Some DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) to establish Internet connections. If you are connected to the Internet through a DSL line, check with your ISP if they use PPPoE. Host Name/Domain Name. Some ISPs require the host name and domain name as identification, if it is not specified, assign on your own or leave it as blank. User Name, Password, Confirm Password. Enter your username, password and confirm again in the fields for the login to the ISP. Service Name. Enter the ISP specified service name or assign on your own if the Service Name is not specified. Packet Size (MTU). The Maximum Transmission Unit of an IP packet. The default value is 1492 Bytes, if your ISP requires a special value, please select from the pull down menu. The default value will work for most cases. Otherwise, contact your ISP for the MTU value. Disconnect after idle time. You can assign an idle time if there is no Internet traffic for the idle time you specified, the modem would be disconnected from the ISP by the gateway automatically. The default value is 5 minutes. Auto Reconnect. The gateway will reconnect your modem to the ISP when you start the Internet access again after the idle time out you specified above. Leave the Auto Reconnect unchecked, the PPPoE connection will be always on, also the Disconnect after idle time will not work. Use Static IP Address. If your ISP does not assign a dynamic address, you will use the static IP address, enter the IP address, subnet mask, and DNS address which your ISP assigned. Use Static DNS. If you want to use your own DNS instead of ISP’s provision, click the checkbox, and give the IP address of the DNS in the field. (At least one for the primary field.) MAC address. Some ISPs allow you to connect to them with specified MAC address only, you can enter the MAC address manually or copy it from a PC which is attached to the Local Port, you just type in its IP address, the gateway will copy the MAC address from that PC. The gateway comes with the factory default MAC address, no need to change the default value if the ISP is not checking the MAC address of your Internet Port. Static IP Configuration If you connect to the Internet using permanent IP address, please select Static IP Configuration from the pull down menu, and fill the ISP specified values in the fields. Host Name/Domain Name. Some ISPs require the host name and domain name as identification, if it is not specified, assign on your own or leave it as blank. IP Address.

Your ISP will assign a gateway address for you, if you could not find one, please contact your ISP. Primary DNS. The domain name server of the ISP or of your own. Secondary DNS. The back up domain name server could be left blank if none. MAC address. Some ISPs allow you to connect to them with specified MAC address only, you can enter the MAC address manually or copy it from a PC which is attached to the Local Port, you just type in its IP address, the gateway will copy the MAC address from that PC. The gateway comes with the factory default MAC address, no need to change the default value if the ISP is not checking the MAC address of your Internet Port. PPTP Configuration Some older modems in Europe use PPTP connection instead of PPPoE, it uses PPP session dial to the modem first, the modem will dial to your ISP, after the connection between the ISP and your modem established, you could share the connection with the modem. Host Name/Domain Name. Some ISPs required the host name and domain name as identification, if it is not specified, assign on your own or leave it as blank. User Name, Password, Confirm Password. Enter your username, password and confirm again in the fields for the login to the ISP. Server IP. Your modem’s IP, you have to set your computer as the same domain as your modem’s (such as the modem’s IP address is 192.168.0.1 and the subnet mask is 255.255.255.0, your PC must be configured as 192.168.0.x, the x is from 2 to 254, the subnet mask should be same as the modem’s 255.255.255.0), then you can reach the modem, if you are not sure that your configuration is right, please try “ping ” in the command line from your PC. If you don’t know the modem’s IP, please refer to the modem’s manual or consult your ISP. Packet Size (MTU). The Maximum Transmission Unit of an IP packet. The default value is 1492 Bytes, if your ISP requires a special value, please select from the pull down menu. The default value will work for most cases. Otherwise, contact your ISP for a specified value. Disconnect after idle time. You can assign an idle time if there is no Internet traffic for the idle time you specified, the modem would be disconnected from the ISP by the gateway automatically. The gateway will reconnect your modem to the ISP when you start the Internet access again. The default value is 5 minutes, if you don’t want the gateway to disconnect your Internet connection automatically, please select 0 minute for permanent Internet connection. Auto Reconnect. If the ISP dropped the connection, or the modem lost the connection accidentally, the gateway will reconnect your modem to the ISP immediately. Use Static IP Address. If your ISP does not assign a dynamic address, you will use the static IP address, enter the IP address, subnet mask, and DNS address which your ISP assigned. Use Static DNS. If you want to use your own DNS instead of ISP’s provision, check this box, and give the IP address of the DNS in the field. (At least one for the primary field.) MAC address. Some ISPs allow you to connect to them with specified MAC address only, you can enter the MAC address manually or copy it from a PC which is attached to the Local Port, you just type in its IP address, the gateway will copy the MAC address from that PC. The gateway comes with the factory default MAC address, no need to change the default value if the ISP is not checking the MAC address of your Internet Port. 3.1.2 LOCAL PORT Configure your gateway’s IP address of the local port here. It has to be a private IP address such as (10.x.x.x, 192.x.x.x are reserved for LAN use). Subnet Mask. The subnet mask determines how many computers are allowed in this network. A class C network with the subnet mask 255.255.255.0 allows maximum 253 users (254-1, because gateway got one already) in your local area network. Usually a class C network is satisfactory for your local network. To enable the DHCP server of the gateway, please click the check box. Start IP address. Specify the start of the IP address you want to assign to DHCP users. The default value is 192.168.1.2. (Please make sure there is no fixed IP address within your DHCP assignation range on the LAN, otherwise your DHCP client cannot get the IP address correctly.) Number of IP address. Assign the number of users allowed to use the DHCP service. The default value is 128 users. Lease Time. A DHCP user’s PC gets an IP address with a lease time, when the lease time is up the IP address assigned to that user’s PC will be expired. The user’s PC must connect to the DHCP server again to get a new IP address. When there are lots of mobile users using DHCP service in your network, select an appropriate time to make sure you manage the IP addresses well, because when the user turns his computer off and leaves, the gateway might not be aware of that IP address is vacant, thus that IP address will be idle there until the lease time expired. The default value of the lease time is 168hours. WINS Server. The Windows Internet Naming Service (WINS) manages each PC’s interaction with the Internet. If you use a WINS server, enter WINS server’s IP Address here. Otherwise, leave this blank. Static DHCP IP & MAC Address. Click Setup in the Local port configuration page to setup the Static DHCP IP. You can assign a fix IP to a computer for the DHCP server. Put the PC’s IP address and MAC address in the fields and click add to add in the list. To delete one PC’s IP address, please select it from the list then click Delete, or click delete all to delete all in the list. 3.1.3 Wireless LAN Click Enable Wireless Access to enable the wireless function of the gateway. SSID. (Service Set Identifier.) The SSID is the network name shared among all points in wireless network. The SSID must be identical for all points in the wireless network. It is case-sensitive and must not exceed 32 characters (use any of the characters on the keyboard). For added security, you should change the default SSID to a unique name. Hide SSID. The gateway will not broadcast the SSID, neither allows the SSID Any connecting to it. Hiding the SSID makes your wireless network more secured, unless the wireless user knows the SSID in advance, otherwise they cannot connect to the gateway. Channel. Select an appropriate channel from the list. The default channel is 10. All devices in your wireless network must be set to the same channel as the gateway’s channel. Operation Mode. The default value is 802.11b/g mixed mode. For the 802.11b/g mixed mode, you can use both 802.11b and 802.11g’s wireless network interface card to connect to it. If you need only one mode either 802.11b or 802.11g, please select from the pull down menu. WEP Security. We strongly recommend you to use the WEP encryption to protect your local network. Otherwise the data might be stolen from your network easily if any other can get your wireless signals. To enable the WEP, choose either 64bit or 128bit for encryption. The default value is Disable, this is for your convenience to connect to the wireless gateway at the first time. A 128bit encryption definitely has more safety than the 64bit encryption, but the 128bit encryption has a higher overhead over the wireless data transfer, it’s a trade off, please choose an appropriate encryption for your network. Key Format. The key format can be in ASCII that is easier to remember, or you can choose the HEX format from the pull down menu.. Passphrase. The gateway can help you to generate random keys, please input a phrase and click Generate. The keys will be generated automatically in the Key fields. Key1-4. Click the radio button to decide which key to use for the wireless data encryption. The wireless network user’s PC must assign to the same key as the gateway’s current key. 3.2 Advanced Items The advanced configurations allow you to manage your gateway safer and smarter. 3.2.1 Advanced Setup >> Access Control List The Access Control List allows you to define Internet access rules for LAN users.

Please refer to the Appendix E for all Update Status messages. Click the Update to check your current status of the DDNS service, or click refresh to refresh the web page display. 3.2.3 Advanced Setup >> Firewall DoS Attack Threshold. When the gateway suffers a continuous attack from the Internet (Which is not a regular connection, usually they are lost of connection requests at a time to consume or exhaust the memory of the gateway.) The gateway will drop the traffics from the attack sources instead of treating them like normal traffics. Please select your own threshold bandwidth from the attack source on the Internet by clicking the radio button. (Normally when you have a smaller bandwidth to the Internet, you will have a correspondently smaller DoS Attack Threshold. Otherwise the DoS function will not work properly.) Block Request from WAN Port. Block request from WAN port feature reinforces your network security by hiding your network ports; this makes it difficult for others to intrude into your network. This feature is enabled by default. But if you host servers on your LAN, you cannot enable this feature, otherwise the users from the Internet cannot reach your servers on the LAN. Block Ping from WAN port. This feature can prevent your network from being “pinged”, or detected by other Internet users. Block PPTP, L2TP, IPSec Request. This feature blocks all VPN connection requests from the hosts outside your network. Use the DMZ host. The DMZ feature allows one local network user to be exposed to the Internet for use of a special-purpose service such as Internet gaming or videoconferencing. DMZ forwards all the ports to this computer. Email Alarm The E-mail alarm feature enables you to receive the access log through e-mails regularly. Click the checkbox, if you want to receive the e-mails from the gateway. Mail Server. This is the e-mail server address on your network or on the Internet. The mail server should relay your mails without user name and password login. Otherwise, the mails cannot be sent out. The standard SMTP port for sending e-mails is 110; if you have special settings, otherwise lease it as default. Subject. The subject will appear as the subject of the e-mails that gateway sent you. So the user can tell by the subject which mail is from the gateway. Send mail to. Please enter your e-mail address or the e-mail address you want the gateway send to. Return address. If your gateway cannot send to the receiptant successfully or the users want to reply a message from the mail, this is the address to reply. E-mail log. You can specify the behavior of the gateway sending the e-mail logs. By clicking the radio button log full, the alarm e-mails will be sent only when the log of the gateway is full. The other option Everyday, the gateway will send e-mails daily weather there is message or not. Time.

A: Some ISPs identify their clients by the accessing MAC address and the host names, therefore, entering these information is the process required to prove they are who they claim to be. MAC address required for global port settings is the adapter address for the device you are now configuring. Most ISPs use automatic registration and do not limit network MAC addresses. But, if they do, you can change your MAC address to meet the registration. Q: What is DMZ? A: DMZ (demilitarized zone), a barrier between the Internet and a company’s Intranet. It is a subnet that contains a firewall and proxy server, which can be in separate servers or in one server. The firewall connects to an external firewall on the Internet side, which may be at the ISP’s location and is often called a “boundary router”. The double firewall architecture adds an extra measure of security for the Intranet. Q: What is Dynamic DNS? A: The Dynamic DNS service, an IP Registry provides a public central database where information such as email addresses, hostnames, Ips etc. can be stored and retrieved. This solves the problems if your DNS server uses an IP associated with dynamic IP. The Dynamic DNS service acts like old-style phone operators: other users call the operator, and ask to speak to you, and the operator, who knows your extension, will make the connection. Every time your computer comes online, it will inform the Dynamic DNS server what the current IP address is. Users who need to connect to your server, through the magic of DNS service, will be sent to the right place. Please visit http://www.dyndns.org for more information. Q: Why “Dynamic DNS”? A: With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register with a Dynamic DNS Client to sue this service. Please go to http://www.dyndns.org for more information. Q: What is Wildcard? A: A wildcard alias is a method that is used to give your hostname multiple identities. If you were to register yourhost.com, everything (*).yourhost.com would be aliased to yourhost.com. This includes host names such as www.yourhost.com or ftp.yourhost.com . Once Wildcard feature was enabled, your host can be reached by *.yourhost.dyndns.org. First, you need to register a dynamic DNS account with www.dyndns.org. To use this service, you must register with the Dynamic DNS client. The Dynamic DNS client service provider will give you a password or key. Refer to what’s Dynamic DNS? Question above for more information. Q: What’s MX (Mail Exchanger)? And why MX? A: The Internet email system for both machines and network connections are prone to error. With this, a chain of email hubs into the email architecture is thus built. If the “primary” mail host goes down, instead of queuing up the mails in the unreliable host on the Internet, they get sent to the “secondary” or “backup” mail exchanger for delivery, until the primary mail server becomes functional again. In technical term, such service is called Backup Mail Exchanger. Q: What is PPPoE (PPP Over Ethernet)? A: PPPoE is know as a dial-up DSL service. It is designed to integrate the broadband services into the current widely deployed, easy-to-use, and low-cost dial-up-access networking infrastructure. Thus, customer can get greater access speed without changing the operation concept. Q: What is MTU? A: A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or frame-based network such as the Internet. The Internet's Transmission Control Protocol uses the MTU to determine the maximum size of each packet in any transmission. Too large an MTU size may mean retransmissions if the packet encounters a router that can't handle that large a packet. Too small an MTU size means relatively more header overhead and more acknowledgements that have to be sent and handled. Most computer operating systems provide a default MTU value that is suitable for most users. In general, Internet users should follow the advice of their Internet service provider (ISP) about whether to change the default value and what to change it to. Appendix C Troubleshooting This chapter is intended to help you troubleshoot problems you may encounter while setting up and using the XAVi route. It also describes some common hardware and software problems and gives some suggestions to troubleshoot them. Refresh your IP address (MS Windows) Sometimes you will wonder what my computer’s IP is or you want to refresh your IP address. There is a tool for this comes with Windows. For Windows 95/98/98se/ME, please click Start > Run, enter winipcfg and click OK. Select the correct Network Adaptor, click release all to release all current configuration first, then click renew all to renew the IP information again. For Windows NT4.0/2000/XP, run ipconfig.exe in DOS mode. (ipconfig.exe/? to list all parameters). Run ipconfig /release and then run ipconfig /renew. IP address conflict When you see the message box prompted for IP address conflict on any of the workstations in the network, this means two or more workstations have the same IP address. If you have setup the device as a DHCP server, on the problem workstation, please run the “winipcfg”, utility, select the correct Network Adapter, click release all to release all current configuration first, then click renew all to renew the IP information again (for Windows 2000/NT4.0/XP, run ipconfig/release and then run ipconfig /renew). If the DHCP function is disabled and static IP addresses are assigned to each workstation, please double check each workstation’s IP address for any duplicate IP. Cannot access the Internet Check the physical connectivity of local network. Check if both the LEDs of local and Global on the product’s front panel are lit. Make sure you are using the correct cables and the cables are connected to the network devices properly. Check the physical connectivity of broadband device. Examine the LED of LAN port and the LED of the broadband signal input on the Cable Modem/xDSL Modem. If the LAN LED is off, make sure you are using the correct cables and the cables are connected to the devices properly. If the LED of the broadband signal is off, please contact your ISP. Check the status of this product. After checking the cabling, you also have to check if you have entered the correct user name and password that your ISP provided. While checking, please note that the information is case sensitive. To check the Internet connection status, open the browser to start the web configuration, select Network Status > WAN IP Status. Check if Link Status displays “Connect successfully”. If not, you may have to contact your ISP to see if their Internet service is available. Check the logical connectivity from your computer to the Internet. Appendix D Government compliance notices FCC compliance This equipment complies with Part 15 of the FCC Rules.
