Scroll down for the output of netstat -nr!
I have a Fedora box with two working NIC's:
DSL, static IP: (NIC 1) ip:168.101.199.6 nm:255.255.255.248 gw:168.101.199.5 dns:168.101.1.3, 168.101.1.9
LAN, has a sonicwall router to Cable modem: (NIC 2) ip:192.168.0.7 nm:255.255.255.0 gw:192.168.0.1 (currently NOT SET so at least the DSL NIC is functional) dns:not needed
With this setup, /nothing/ works. Can't ping anything, can't browse from the box locally, nothing. However if I remove the gateway on NIC 2 (192.168.0.1), then I can at least browse through NIC 1 and it can be pinged. However--the LAN interface is still useless, can't ping it.
The reverse works the same. Remove the GW on NIC 1 (168.101.199.5) and place it on NIC 2 (192.168.0.1) then I can browse through NIC 2 on the Cable modem side, but then the DSL NIC becomes useless (can't ping).
So I am asking, what is the trick to make BOTH interfaces work and if the server needs to go out onto the net, it will by default browse out on the DSL side of things? I would like to be able to manage the server and provide file services from the LAN side.

You need to have the default route set to the cable modem and a specific route in place for the internal lan, so that for everything except the internal lan, it will go out to the cable modem. Do a "netstat -nr", or a "route print", and let's see what you have.

Again, I think this output is with my LAN NIC disabled, again: the LAN NIC doesn't have a gw because /nothing/ works when it is defined. Goal: be able to provide management and file services from the LAN NIC and still function with the DSL NIC.
Thanks,
Julian
