DI-1162 Remote Access Router

•Name – this is a 12 character (maximum), alphanumeric, user- defined name, used to identify the filter.

•Direction – this defines the direction of the packet relative to the Interface parameter below.

•State – this is used to define the routing decision applied to the packet. The three routing decisions are described:

1.forward – this allows the routing of the packet, if it has met the criteria of the corresponding filter.

2.drop – this drops (doesn’t allow routing for) a specific packet that has met the criteria of the corresponding filter.

3.disable – this does not apply the IP filter.

•Interface – this applies the filter to a specific interface, LAN or one of the three WANs.

•Protocol Type – this is a protocol identifier, as assigned by the Internet Assigned Numbers Authority (IANA). The values of this identifier are described in RFC-1700. This router supports the following:

4.protocol type = 1, this is Internet Control Message (ICMP), defined in RFC 792.

5.protocol type = 6, this is Transmission Control (TCP), defined in RFC 793.

6.protocol type = 17, this is User Datagram (UDP), defined in RFC 798.

•Src IP – this is the source address in the IP header of this packet.

•Src Netmask – this mask is bit-wise AND’d with the source IP address, and compared to the IP address of the incoming interface, for which the packet arrived.
