Defining Filters and Firewalls

Example filters

6-18 Preliminary January 30, 1998 Pipeline User’s Guide

Dst Port #=N/A

TCP Estab=N/A

These conditions specify the loopback address in the Src Mask and Src Adrs

fields. If an incoming packet has this address, it will not be forwarded onto

the Ethernet.

Close the current Input filter, and then open In filter 03.

Set Valid=Yes and Type=IP, and then open the IP submenu and specify the

following conditions:

Ip...

>Forward=Yes

Src Mask=0.0.0.0

Src Adrs=0.0.0.0

Dst Mask=0.0.0.0

Dst Adrs=0.0.0.0

Protocol=0

Src Port Cmp=None

Src Port #=N/A

Dst Port Cmp=None

Dst Port #=N/A

TCP Estab=N/A

These conditions specify every other source address (0.0.0.0) If an incoming

packet has any non-local source address, it will not be forwarded onto the

Ethernet.

Close the Input filter, and then return to the top level of the “no spoofing”

Filter profile.

Open the Output Filters submenu, and select Out filter 01.
