    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.
  • Page 100 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: Filter Name : Out_Filter1 Protocol...
  • Page 101 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.

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.

    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.
