2. Select from the desired Log options described in the following table, and then click Save/Apply.

Option Log Log level

Description Indicates whether the system is currently recording events. The user can enable or disable event logging. By default, it is disabled. To enable it, tick Enable and then Apply button. 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 Router 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 following log levels are: 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. Allows the user to select the logged events and displays on the View System Log page for events of this level and above to the highest Emergency level. Allows you to specify whether events should be stored in the local memory, or be sent to a remote syslog server, or both simultaneously. If remote mode is selected, view system log will not be able to display events saved in the remote syslog 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.

8.6 Save and Reboot

The Save/Reboot option saves the configurations and reboots the router. Close the DSL Router Configuration window and wait for 2 minutes before reopening your web browser. If necessary, reconfigure your PC's IP address to match your new configuration.

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 filtering rules 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, web page. Outgoing IP Filtering: Helps in setting rules to DROP packets from the LAN interface. By default if Firewall is Enabled all IP traffic from LAN is allowed. By setting up one or more filters, particular packet types coming from the LAN can be dropped. Filter Name: User defined Filter Name. Protocol: Can take on any values from: TCP/UDP, TCP, UDP or ICMP Source IP Address/Source Subnet Mask: Packets with the particular "Source IP Address/Source Subnet Mask" combination will be dropped. Source Port: This can take on either a single port number or a range of port numbers. Packets having a source port equal to this value or falling within the range of port numbers(portX : portY) will be dropped. Destination IP Address/Destination Subnet Mask: Packets with the particular "Destination IP Address/Destination Subnet Mask" combination will be dropped. Destination Port: This can take on either a single port number or a range of port numbers. Packets having a destination port equal to this value or falling within the range of port numbers(portX : portY) will be dropped.
Examples: 1. Filter Name Protocol Source Address Source Subnet Mask Source Port Dest. Address Dest. Sub. Mask Dest. Port : Out_Filter1 : TCP : 192.168.1.45 : 255.255.255.0 : 80 :NA : NA : NA
This filter will Drop all TCP packets coming from LAN with IP Address/Sub. Mask 192.168.1.45/24 having a source port of 80 irrespective of the destination. All other packets will be Accepted. 2. Filter Name Protocol Source Address Source Subnet Mask Source Port Dest. Address Dest. Sub. Mask Dest. Port : Out_Filter2 : UDP : 192.168.1.45 : 255.255.255.0 : 5060:6060 :172.16.13.4 : 255.255.255.0 : 6060:7070
This filter will drop all UDP packets coming from LAN with IP Address/Sub.Mask 192.168.1.45/24 and a source port in the range of 5060 to 6060, destined to 172.16.13.4/24 and a destination port in the range of 6060 to 7070 Incoming IP Filtering: Helps in setting rules to ACCEPT packets from the WAN interface. By default all incoming IP traffic from WAN is Blocked, if the Firewall is Enabled. By setting up one or more filters, particular packet types coming from the WAN can be Accepted. Filter Name: User defined Filter Name. Protocol: Can take on any values from: TCP/UDP, TCP, UDP or ICMP Source IP Address/Source Subnet Mask: Packets with the particular "Source IP Address/Source Subnet Mask" combination will be accepted. Source Port: This can take on either a single port number or a range of port numbers. Packets having a source port equal to this value or falling within the range of port numbers(portX : portY) will be accepted. Destination IP Address/Destination Subnet Mask: Packets with the particular "Destination IP Address/Destination Subnet Mask" combination will be accepted. Destination Port: This can take on either a single port number or a range of port numbers. Packets having a destination port equal to this value or falling within the range of port numbers(portX : portY) will be accepted.

Other MAC Address: If restrictions are to be applied to a device other than the one on which the browser is running, the MAC address of that LAN device is entered. Days of the Week: Days of the week, when the restrictions are applied. Start Blocking Time: The time when restrictions on the LAN device are put into effect. End Blocking Time: The time when restrictions on the LAN device are lifted. 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 When this rule i.e. FilterJohn is entered, a LAN device with MAC Address of 00:25:46:78:63:21 will be restricted access to the outside network on Mondays, Wednesdays and Fridays, from 2pm to 6pm. On all other days and time this device will have access to the outside Network.
