131 8.2 System Log This function allows a system log to be kept and viewed upon request. Follow the steps below to configure, enable, and view the system log. STEP 1: Click Configure System Log, as shown below (circled in Red). STEP 2: Select desired options and click Apply/Save. Consult the table below for detailed descriptions of each system log option. Option Description Log Indicates whether the system is currently recording events. The user can enable or disable event logging. By default, it is disabled. To enable it, select the Enable radio button and then click Apply/Save.
132 Option Description Log Level Allows you to configure the event level and filter out unwanted events below this level. The events ranging from the highest critical level “Emergency” down to this configured level will be recorded to the log buffer on the AR-5313u SDRAM. When the log buffer is full, the newer event will wrap up to the top of the log buffer and overwrite the old event. By default, the log level is “Debugging”, which is the lowest critical level. The log levels are defined as follows:  Emergency = system is unusable  Alert = action must be taken immediately  Critical = critical conditions  Error = Error conditions  Warning = normal but significant condition  Notice= normal but insignificant condition  Informational= provides information for reference  Debugging = debug-level messages Emergency is the most serious event level, whereas Debugging is the least important. For instance, if the log level is set to Debugging, all the events from the lowest Debugging level to the most critical level Emergency level will be recorded. If the log level is set to Error, only Error and the level above will be logged. Display Level Allows the user to select the logged events and displays on the View System Log window for events of this level and above to the highest Emergency level. Mode Allows you to specify whether events should be stored in the local memory, or be sent to a remote system log server, or both simultaneously. If remote mode is selected, view system log will not be able to display events saved in the remote system log server. When either Remote mode or Both mode is configured, the WEB UI will prompt the user to enter the Server IP address and Server UDP port. STEP 3: Click View System Log.

144 Appendix A - Firewall STATEFUL PACKET INSPECTION Refers to an architecture, where the firewall keeps track of packets on each connection traversing all its interfaces and makes sure they are valid. This is in contrast to static packet filtering which only examines a packet based on the information in the packet header. DENIAL OF SERVICE ATTACK Is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have. Various DoS attacks the device can withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf Attack, and Tear Drop. TCP/IP/PORT/INTERFACE FILTER These rules help in the filtering of traffic at the Network layer (i.e. Layer 3). When a Routing interface is created, Enable Firewall must be checked. Navigate to Advanced Setup  Security  IP Filtering. OUTGOING IP FILTER Helps in setting rules to DROP packets from the LAN interface. By default, if the Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more filters, specific packet types coming from the LAN can be dropped. Example 1: Filter Name : Out_Filter1 Protocol : TCP Source IP address : 192.168.1.45 Source Subnet Mask : 255.255.255.0 Source Port : 80 Dest. IP Address : NA Dest. Subnet Mask : NA Dest. Port : NA This filter will Drop all TCP packets coming from the LAN with IP Address/Subnet Mask of 192.168.1.45/24 having a source port of 80 irrespective of the destination. All other packets will be Accepted. Example 2: Filter Name : Out_Filter2 Protocol : UDP Source IP Address : 192.168.1.45 Source Subnet Mask : 255.255.255.0 Source Port : 5060:6060 Dest. IP Address : 172.16.13.4 Dest. Subnet Mask : 255.255.255.0 Dest. Port : 6060:7070 This filter will drop all UDP packets coming from the LAN with IP Address / Subnet Mask of 192.168.1.45/24 and a source port range of 5060 to 6060, destined to 172.16.13.4/24 and a destination port range of 6060 to 7070.
145 INCOMING IP FILTER Helps in setting rules to Allow or Deny packets from the WAN interface. By default, all incoming IP traffic from the WAN is Blocked, if the Firewall is Enabled. By setting up one or more filters, specific packet types coming from the WAN can be Accepted. Example 1: Filter Name : In_Filter1 Protocol : TCP Policy : Allow Source IP Address : 210.168.219.45 Source Subnet Mask : 255.255.0.0 Source Port : 80 Dest. IP Address : NA Dest. Subnet Mask : NA Dest. Port : NA Selected WAN interface : br0 This filter will ACCEPT all TCP packets coming from WAN interface “br0” with IP Address/Subnet Mask 210.168.219.45/16 with a source port of 80, irrespective of the destination. All other incoming packets on this interface are DROPPED. Example 2: Filter Name : In_Filter2 Protocol : UDP Policy : Allow Source IP Address : 210.168.219.45 Source Subnet Mask : 255.255.0.0 Source Port : 5060:6060 Dest. IP Address : 192.168.1.45 Dest. Sub. Mask : 255.255.255.0 Dest. Port : 6060:7070 Selected WAN interface : br0 This rule will ACCEPT all UDP packets coming from WAN interface “br0” with IP Address/Subnet Mask 210.168.219.45/16 and a source port in the range of 5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range of 6060 to 7070. All other incoming packets on this interface are DROPPED. MAC LAYER FILTER These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in Bridge mode. After a Bridge mode connection is created, navigate to Advanced Setup  Security  MAC Filtering in the WUI. Example 1: Global Policy : Forwarded Protocol Type : PPPoE Dest. MAC Address : 00:12:34:56:78:90 Source MAC Address : NA Src. Interface : eth1 Dest. Interface : eth2 Addition of this rule drops all PPPoE frames going from eth1 to eth2 with a Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC Address. All other frames on this interface are forwarded.
146 Example 2: Global Policy : Blocked Protocol Type : PPPoE Dest. MAC Address : 00:12:34:56:78:90 Source MAC Address : 00:34:12:78:90:56 Src. Interface : eth1 Dest. Interface : eth2 Addition of this rule forwards all PPPoE frames going from eth1 to eth2 with a Destination MAC Address of 00:12:34:56:78 and Source MAC Address of 00:34:12:78:90:56. All other frames on this interface are dropped. DAYTIME PARENTAL CONTROL This feature restricts access of a selected LAN device to an outside Network through the AR-5313u , as per chosen days of the week and the chosen times. Example: User Name : FilterJohn Browser's MAC Address : 00:25:46:78:63:21 Days of the Week : Mon, Wed, Fri Start Blocking Time : 14:00 End Blocking Time : 18:00 With this rule, a LAN device with MAC Address of 00:25:46:78:63:21 will have no access to the WAN on Mondays, Wednesdays, and Fridays, from 2pm to 6pm. On all other days and times, this device will have access to the outside Network.

161 E2.1 PPP over ETHERNET (PPPoE) – IPv4 STEP 1: Select the PPP over Ethernet radio button and click Next. You can also enable IPv6 by ticking the checkbox  at the bottom of this screen. STEP 2: On the next screen, enter the PPP settings as provided by your ISP. Click Next to continue or click Back to return to the previous step.
162 The settings shown above are described below. PPP SETTINGS The PPP Username, PPP password and the PPPoE Service Name entries are dependent on the particular requirements of the ISP. The user name can be a maximum of 256 characters and the password a maximum of 32 characters in length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP.
163 ENABLE FULLCONE NAT This option becomes available when NAT is enabled. Known as one-to-one NAT, all requests from the same internal IP address and port are mapped to the same external IP address and port. An external host can send a packet to the internal host, by sending a packet to the mapped external address. DIAL ON DEMAND The AR-5313u can be configured to disconnect if there is no activity for a period of time by selecting the Dial on demand checkbox . You must also enter an inactivity timeout period in the range of 1 to 4320 minutes. PPP IP EXTENSION The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specifically requires this setup, do not select it. PPP IP Extension does the following:  Allows only one PC on the LAN.  Disables NAT and Firewall.  The device becomes the default gateway and DNS server to the PC through DHCP using the LAN interface IP address.  The device extends the IP subnet at the remote service provider to the LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.  The device bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the device’s LAN IP address.  The public IP address assigned by the remote side using the PPP/IPCP protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the PC LAN interface through DHCP. Only one PC on the LAN can be connected to the remote, since the DHCP server within the device has only a single IP address to assign to a LAN device. ENABLE NAT If the LAN is configured with a private IP address, the user should select this checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot. On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN side is using a public IP), this checkbox  should not be selected to free up system resources for better performance. ENABLE FIREWALL If this checkbox  is selected, the Security submenu will be displayed on the Advanced Setup menu after reboot. If firewall is not necessary, this checkbox  should not be selected to free up system resources for better performance. USE STATIC IPv4 ADDRESS Unless your service provider specially requires it, do not select this checkbox . If selected, enter the static IP address in the IPv4 Address field. Don’t forget to adjust the IP configuration to Static IP Mode as described in section 3.2.
164 FIXED MTU Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which the layer can pass onwards. This value is 1500 for PPPoA. ENABLE PPP DEBUG MODE When this option is selected, the system will put more PPP connection information into the system log. This is for debugging errors and not for normal usage. BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS (This option is hidden when PPP IP Extension is enabled) When Enabled, this creates local PPPoE connections to the WAN side. Enable this option only if all LAN-side devices are running PPPoE clients, otherwise disable it. The AR-5313u supports pass-through PPPoE sessions from the LAN side while simultaneously running a PPPoE client from non-PPPoE LAN devices. ENABLE IGMP MULTICAST PROXY Tick the checkbox  to enable Internet Group Membership Protocol (IGMP) multicast. This protocol is used by IPv4 hosts to report their multicast group memberships to any neighboring multicast routers. NO MULTICAST VLAN FILTER Tick the checkbox  to Enable/Disable multicast VLAN filter. Enable WAN interface with base MAC Enable this option to use the router’s base MAC address as the MAC address for this WAN interface. STEP 3: Choose an interface to be the default gateway. Click Next to continue or click Back to return to the previous step.
165 Select DNS Server Interface from available WAN interfaces OR enter static DNS server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or static IPoE protocol is configured, Static DNS server IP addresses must be entered. Click Next to continue or click Back to return to the previous step.
166 STEP 5: The WAN Setup - Summary screen shows a preview of the WAN service you have configured. Check these settings and click Apply/Save if they are correct, or click Back to modify them. After clicking Apply/Save, the new service should appear on the main screen. To activate it you must reboot. Go to Management  Reboot and click Reboot.
167 E2.2 IP over ETHERNET (IPoE) – IPv4 STEP 1: Select the IP over Ethernet radio button and click Next. For tagged service, enter valid 802.1P Priority and 802.1Q VLAN ID. For untagged service, set -1 to both 802.1P Priority and 802.1Q VLAN ID. STEP 2: The WAN IP settings screen provides access to the DHCP server settings. You can select the Obtain an IP address automatically radio button to enable DHCP (use the DHCP Options only if necessary). However, if you prefer, you can instead use the Static IP address method to assign WAN IP address, Subnet Mask and Default Gateway manually.
168 Click Next to continue or click Back to return to the previous step. STEP 3: This screen provides access to NAT, Firewall and IGMP Multicast settings. Enable each by selecting the appropriate checkbox . Click Next to continue or click Back to return to the previous step.
169 ENABLE NAT If the LAN is configured with a private IP address, the user should select this checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.

The IP unnumbered interface can "borrow" the IP address of another interface already configured on the router, which conserves network and address space. LAUNCH DHCP6C FOR ADDRESS ASSIGNMENT (IANA) The Internet Assigned Numbers Authority (IANA) is a department of ICANN responsible for coordinating some of the key elements that keep the Internet running smoothly. Whilst the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the Internet to be globally coordinated, and this coordination role is undertaken by IANA. Specifically, IANA allocates and maintains unique codes and numbering systems that are used in the technical standards (“protocols”) that drive the Internet. IANA’s various activities can be broadly grouped in to three categories: • Domain Names IANA manages the DNS Root, the .int and .arpa domains, and an IDN practices resource. • Number Resources IANA coordinates the global pool of IP and AS numbers, providing them to Regional Internet Registries. • Protocol Assignments Internet protocols’ numbering systems are managed by IANA in conjunction with standards bodies. LAUNCH DHCP6C FOR PREFIX DELEGATION (IAPD) An Identity Association for Prefix Delegation (IAPD) is a collection of prefixes assigned to a requesting device. A requesting device may have more than one IAPD; for example, one for each of its interfaces. A prefix-delegating router (DHCPv6 server) selects prefixes to be assigned to a requesting router (DHCPv6 client) upon receiving a request from the client. The server can select prefixes for a requesting client by using static and dynamic assignment mechanisms. Administrators can manually configure a list of prefixes and associated preferred and valid lifetimes for an IAPD of a specific client that is identified by its DUID. When the delegating router receives a request from a client, it checks if there is a static binding configured for the IAPD in the client’s message. If a static binding is present, the prefixes in the binding are returned to the client. If no such binding is found, the server attempts to assign prefixes for the client from other sources. An IPv6 prefix delegating router can also select prefixes for a requesting router based on an external authority such as a RADIUS server using the Framed-IPv6-Prefix attribute. FIXED MTU Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which the layer can pass onwards. This value is 1492 for PPPoE. ENABLE PPP DEBUG MODE When this option is selected, the system will put more PPP connection information into the system log. This is for debugging errors and not for normal usage.
186 BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS (This option is hidden when PPP IP Extension is enabled) When Enabled, this creates local PPPoE connections to the WAN side. Enable this option only if all LAN-side devices are running PPPoE clients, otherwise disable it. The AR-5313u supports pass-through PPPoE sessions from the LAN side while simultaneously running a PPPoE client from non-PPPoE LAN devices. Enable IGMP Multicast Proxy Tick the checkbox  to enable Internet Group Membership Protocol (IGMP) multicast. This protocol is used by IPv6 hosts to report their multicast group memberships to any neighboring multicast routers. No Multicast VLAN Filter Tick the checkbox  to Enable/Disable multicast VLAN filter. ENABLE MLD MULTICAST PROXY Multicast Listener Discovery (MLD) is a component of the Internet Protocol Version 6 (IPv6) suite. MLD is used by IPv6 routers for discovering multicast listeners on a directly attached link, much like IGMP is used in IPv4. The protocol is embedded in ICMPv6 instead of using a separate protocol. WAN interface with base MAC Enable this option to use the router’s base MAC address as the MAC address for this WAN interface. STEP 3: Choose an interface to be the default gateway. Also, select a preferred WAN interface as the system default IPv6 gateway (from the drop- down box). Click Next to continue or click Back to return to the previous step.
187 STEP 4: Select DNS Server Interface from available WAN interfaces OR enter static DNS server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or static IPoE protocol is configured, Static DNS server IP addresses must be entered. Select the configured WAN interface for IPv6 DNS server information OR enter the static IPv6 DNS server Addresses. Note that selecting a WAN interface for IPv6 DNS server will enable DHCPv6 Client on that interface. Click Next to continue or click Back to return to the previous step.

190 STEP 2: The WAN IP settings screen provides access to the DHCP server settings. You can select the Obtain an IP address automatically radio button to enable DHCP (use the DHCP Options only if necessary). However, if you prefer, you can use the Static IP address method instead to assign WAN IP address, Subnet Mask and Default Gateway manually. Enter information provided to you by your ISP to configure the WAN IPv6 settings. Notice: If “Obtain an IPv6 address automatically” is chosen, DHCP client will be enabled on this WAN interface. If “Use the following Static IPv6 address” is chosen, enter the static WAN IPv6 address. If the address prefix length is not specified, it will be default to /64.
