[NTLUG:Discuss] Which nic the gateway?

[Michael Barnes]

I've got a Dell laptop running SUSE 9.2.  It has a built-in NIC (eth0) 
and a second NIC (eth1) in the docking station.  When I come into the 
office and put it into the dock and fire it up, it pulls DHCP from the 
server.  My problem is, when using the dock, DHCP assigns a static IP 
address, but assigns the gateway as reachable via eth0.  Then I have to 
go to command line and ifdown eth0, then ifup eth1 to re-pull DHCP and 
set the gateway reached via eth1.  Once I do that, then all is happy 
until I reboot.

I cannot seem to find anything in the DHCP configuration which allows me 
to specify a specific NIC to use, or anything in the laptop that lets me 
turn off the laptop NIC when in the dock.

Thanks for any ideas,
Michael
