Multiple lan cards acting as a router

[Alan Riggs]

Your subscripts for the card instances and default routes do not agree. You are basically setting the second card as the opening to the default gateway for the first card. Just make your subscripts agree, recycle network services (reboot or clear improper routes with route delete), and you should be fine.

use ndd command to avoid forwarding:

ndd ip_forwarding 0

See man ndd; maybe syntax is not exactly so.

Hi :

Here is the syntax for ndd.
# ndd -set /dev/ip ip_forwarding 0

There are three different values that could be used :

0 disables forwarding completely
1 always forwards all packets
2 only forwards packets if the number of logical
interfaces on the system is 2 or more.
This is the default behavior.
