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.
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 : Out_Filter1 Protocol : TCP Source Address : 192.168.1.45 Source Subnet Mask : 255.255.255.0 Source Port : 80 Dest. Address :NA Dest. Sub. Mask : NA Dest. Port : NA This filter will Drop all TCP packets coming from LAN with IP Address/Sub.
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.
2. Filter Name : In_Filter2 Protocol : UDP Source Address : 210.168.219.45 Source Subnet Mask : 255.255.0.0 Source Port : 5060:6060 Dest. Address :192.168.1.45 Dest. Sub. Mask : 255.255.255.0 Dest. Port : 6060:7070 This rule will ACCEPT all UDP packets coming from WAN interface mer_0_35/nas_0_35 with IP Address/Sub.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.
Source MAC Address: Of the form, XX:XX:XX:XX:XX:XX. Frames with this particular source address will be Forwarded/Dropped depending on whether the Global Policy is Blocked/Forwarded. Frame Direction: LAN <=> WAN --> All Frames coming/going to/from LAN or to/from WAN. WAN => LAN --> All Frames coming from WAN destined to LAN. LAN => WAN --> All Frames coming from LAN destined to WAN User needs to select the interface on which this rule is applied. Examples: 1.
Addition of this rule forwards all PPPoE frames going from WAN-side to LAN-side with a Dest. MAC Addr. of 00:12:34:56:78 and Source MAC Addr. of 00:34:12:78:90:56 on the br_0_34 WAN interface. 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 router, as per chosen days of the week and the chosen times. User Name: Name of the Filter.

Appendix D: SSH Client Linux OS comes with ssh client. MicroSoft Windows does not have ssh client but there is a public domain one “putty” that you can download. http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html To access the router using Linux ssh client: From LAN: Use the router WEB UI to enable SSH access from LAN. (default is enabled) type: ssh -l admin 192.168.1.1 From WAN: In the router, use WEB UI to enable SSH access from WAN.
