RIP Send Version Select the format and the broadcasting method of the RIP packets that the Gateway sends. Choices are: • RIP1 • RIP2 • RIP1/2 Your selection should match the version supported by other routers on your network. RIP Receive Version Select the format and the broadcasting method of the RIP packets that the Gateway receives. Choices are: • RIP1 • RIP2 • RIP1/2 Your selection should match the version supported by other routers on your network. Update Interval Specify how often, in seconds, the Gateway sends routing-update messages. Default Metric Enter a number by which the metric value for the path increases when the Gateway receives a routing update that includes changes to an entry. Choices are 1 – 15. Default is 1. Authentication Type Select the authentication mechanism used, if any. Choices are: • No Authentication = no authentication is used. If you keep this default setting, the Authentication Key & ID fields are gray and unavailable. • Simple Password = an authentication method where a clear text password is sent to participating neighbors on the network. This selection sends the authenticating password over the network, possible making it available to individuals who can access packets off the network. Do not use this option as part of your security strategy, Rather, use it to avoid accidental changes to the routing infrastructure. If you select this setting, the first field in the Authentication Key & ID option becomes available for entering the password. • md5 = an authentication method that works much like Simple Password authentication, except that MD5 does not send the key over the network. Instead, a router uses the MD5 algorithm to produce a message digest of the key (also called a hash). The router sends the message digest instead of the key itself, which ensures that no one can eavesdrop on the network and learn keys during transmission. If you select this setting, the first field in the Authentication Key & ID option becomes available for entering the key and the second field becomes available for entering the ID. Authentication Key & ID Specify the appropriate information based on the Authentication Type selected: • No Authentication = no entry required. • Simple Password = in the first field, enter the clear-text password to be used for authentication. The second field requires no entry, and is gray and unavailable. • md5 = in the first field, enter the MD5-hash password. In the second field, enter the Key Identifier that identifies the key used to create the authentication data for this message. Neighbor IP Enter the IP address of the Gateway’s RIP neighbor router.
84 SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual DMZ Page Path: Advanced > DMZ If you have a local client computer that cannot run an Internet application properly behind the firewall, you can configure the computer for unrestricted two-way Internet access by defining it as a Virtual DMZ host. A DMZ allows a single computer on your LAN to expose its ports to the Internet. When doing this, the exposed computer is no longer “behind” the firewall. Therefore, placing a computer in the DMZ should be considered temporary because the firewall is no longer able to provide any security to it. Figure 51. DMZ Page Table 25. DMZ Page Options Option Description Enable DMZ Enables or disables the Gateway’s DMZ setting. • Enabled = Gateway’s DMZ feature is enabled. • Disabled = Gateway’s DMZ feature is disabled. This selection makes the SMZ Host field unavailable. DMZ Host Enter the IP addresses of the computer to be used as the DMZ server.
85 SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual QoS Page Path: Advanced > QoS The QoS page lets you configure the Gateway to deliver better resource reservation control. Wireless networks offer an equal opportunity for all devices to transmit data from any type of application. Although this is acceptable for most applications, multimedia audio and video applications are particularly sensitive to the delay and throughput variations that result from this “equal opportunity” wireless access method. For multimedia applications to run well over a wireless network, a Quality of Service (QoS) mechanism is required to prioritize traffic types and provide an “enhanced opportunity” wireless access method. The QoS page lets you enable or disable QoS settings. After making your selections, click the SAVE button to apply them. You can change QoS settings without having to reboot the Gateway. Figure 52. QoS Page
86 SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual Table 26. QoS Page Options Option Description QoS for WiFi Multimedia (WMM) Enables or disables QoS for WMM. Choices are: • Enabled = QoS is enabled for WMM. • Disabled = QoS is disabled for WMM. QoS for LAN Enables or disables QoS for WMM. Choices are: • Enabled = QoS is enabled for WMM. • Disabled = QoS is disabled for WMM.
87 SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual Device Discovery Page Path: Advanced > Device Discovery Universal Plug and Play (UPnP) is an architecture that allows for dynamic connectivity between devices on a network. The goal of UPnP is to support zero-configuration, "invisible" networking of devices including intelligent appliances, PCs, printers and other smart devices using standard protocols. Using UPnP, devices can add themselves to a network dynamically, without requiring user intervention or configuration. A UPnP-enabled device can obtain an IP address, advertise its capabilities, learn about other connected UPnP devices, and then communicate directly with those devices. The same device can end its connection cleanly when it wishes to leave the UPnP community. Using the Device Discovery page, the Gateway can discover all UPnP-enabled devices on the network. After making your selections, click the SAVE button to apply them. Figure 53. Device Discovery Page
88 SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual Table 27. Device Discovery Page Options Option Description Enable UPnP Determines whether the Gateway’s UPnP capabilities are enabled or disabled. Choices are: • Enabled = enables the Gateway’s UPnP capabilities. • Disabled = disables the Gateway’s UPnP capabilities. Advertisement Period Specify how often, in seconds, the Gateway broadcasts its UPnP information. This value can range from 1 to 2147483648 seconds. Short durations ensure that control points have current device status at the expense of additional network traffic. Long durations can compromise the freshness of the device status, but can significantly reduce network traffic. Time To Live Configure the number of hops (steps) for the advertisement time to live. The time to live for the advertisement is measured in hops for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default setting should be fine for most home networks. If some of your devices are not being updated or reached correctly, you can increase this value slightly.
89 SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual VPN Global Page Path: Advanced > VPN > Global A Virtual Private Network (VPN) is a technology designed to increase the security of information transferred over the Internet. A VPN creates a private encrypted tunnel from the user's computer, through the local wireless network, through the Internet, all the way to the corporate servers and database. The Gateway supports the Internet Protocol Security (IPSec) to secure IP traffic. IPSec builds “virtual tunnels” between a local and remote subnet for secure communication between two networks. This connection is commonly known as a Virtual Private Network (VPN). Alternatively, tunneling protocols such as Point-to-Point Tunneling Protocol (PPTP) and Layer Two Tunneling Protocol (L2TP) can be used to achieve a secure connection (such as to a corporate LAN) over the Internet. These tunneling protocols can optionally be secured themselves using IPSec. Using the Global settings page, you can enable or disable the Gateway’s VPN settings. Figure 54. Global Settings Page
90 SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual Table 28. Global Settings Page Options Option Description Enable PPTP Lets you enable or disable PPTP tunneling. Enable IPSEC Lets you enable or disable L2TP tunneling. Pre-shared Key Enter a “pass code.” This pass code must be the same at both the local and the remote side. Both ends of the tunnel must use the same key; otherwise, the VPN tunnel cannot be established.

Remote Host Address Enter the IP address of the remote host at the other end of the VPN tunnel. Remote Host Netmask Enter the netmask of the remote host other end of the VPN tunnel. #Key Management IKE Negotiation Mode Select the IKE operating mode. Choices are: • Main = creates an encrypted channel before exchanging the identities. • Aggressive = quicker than Main Mode, exchanges endpoint IDs in “clear text”, while performing Diffie-Hellman (DH) exchange and establishing the secure channel. Aggressive Mode is less secure than Main Mode. IKE DH Group Select the DH group that will produce the secret shared value. The strength of the technique is that it allows participants to create the secret value over an unsecured medium without passing the secret value through the wire. You can select from three DH groups. The size of the prime modulus used in each group's calculation differs as follows: • Group 2 = D-H Group 2 algorithm is used for the Diffie-Hellman Key Exchange. DH Group 2 uses a 1024-bit encryption. • Group 5 = D-H Group 5 algorithm is used for the Diffie-Hellman Key Exchange. DH Group 5 uses a 1536-bit encryption. • Group 6 = D-H Group 6 algorithm is used for the Diffie-Hellman Key Exchange. DH Group 6 offers the highest key size and the highest level of security. IKE Pre-shared Key Enter a “pass code”. The pass code must be the same at both the local and the remote side. Both ends of the tunnel must use the same key; otherwise, the VPN tunnel cannot be established. IKE Hash Checks that the data has not changed in transmission. Both ends of the tunnel must use the same setting; otherwise, the VPN tunnel cannot be established.
