'Scuse the dumb newbie question....
I have a Shorewall firewall machine that has 3 ethernet cards: 2 as gateways to the internet and the third interfacing to our lan. Behind each of the 2 internet-facing ethernet cards are 2 adsl modems, which have IP addresses 192.168.1.1 (behind eth2) and 192.168.1.2 (behind eth1).
I can't get to one of those modem but can to the other, presumably because it is using a default gateway... I suspect the modems should have be properly setup on separate sub-nets... Anyway, I want to be able to get to both ADSL modems from the LAN. What do I need to do to the routing table? Which commands?
Here is the existing netstat - rn output:
