Multiple NIC set up
«

This is a general networking question that's probably trivial to those who know what they're doing but its turning into a real time sink for me:
I have a PC with two NICs as eth0 and eth1.
I want to be able to network with my office LAN (IP addresses 10.0.X.X) on eth1 and a DSL router at 192.168.0.1 on eth0. Internet traffic has to go through the DSL router and not through the LAN firewall at 10.0.2.1 as a large part of the project here is to test access to internal and DMZ hosts from an "external" host.
I do not need to route traffic from other hosts to the DSL router - I just need internet traffic originating on this host to go out on the DSL line and to be able to ssh to it from either side.
I have complete freedom in configuring the TC host as far as assigning static IPs or using DHCP.
The DSL gateway at 192.168.0.1 acts a a caching DNS server as does the gateway/firewall at 10.0.2.1.
I'm thinking a couple of "ifconfig"s and "route add" or two will do the job, but I have yet to get both interfaces working at the same time.
Can anyone help me with this?

Set eth0 as default route, done. Using static IPs would probably be best for a more complex setup like this.
edit: Start with everything down, no dhcp.
ifconfig eth0 blabla up
ifconfig eth1 blabla up
route add default gw 192.168.0.1 dev eth0

Thanks curaga!
I'm hoping to get some time to tinker with it today, but it already is working better than any of my previous attempts.
