Re: simple dhcp questions...
That is weird. The option routers line is indeed supposed to set the default
gateway. This works fine for me. I will say though that if your laptop is
actually running WinNT and you have two ethernet interfaces (one pcmcia, one
in the docking station) this is pretty much standard behavior. You have to
release the one you're not using using NT's ipconfig command.
