Re: [TCLUG:2546] Configuring for 2 Network Adapters

[Jon Kotek <kotek@oath.net>]

I am doing the same thing but with MediaOneExpress, the thing I am
wondering about is my surfboard router cannot go 100MB so it was pointless
to configure my 10/100 905 card.  I would assume the Netspeed is the same
way.  Besides, you will never see that kind of speed out of the internet.
Now I want my Linux box to do DHCP serving to all my other machines, I have
been told that doing that with two nics is touchy, anyone done this??
