Re: Problems getting 2 NICs to work.

[Kevin Kimmell <kevin@xxxxxxxxxxxxxxxx>]

Okay...

Yes, I have two full class c networks from 2 different ISPs. I am simply 
trying to assign one IP address from each ISP to the two NICs in these 
machines. When both NICs are acivated, they both show up in a cat of 
/proc/interrupts.

Another observation that I've made (I'm unsure if it even means anything):

When I "ifup eth1" the default route moves from the gateway of eth0 to 
the gateway of eth1 and then when I ifdown eth1 the default gateway 
ceases to exist.

Strange things...
