I set that up recently and found it refreshingly simple. Just load a packet driver (finding the right packet driver for your card is the biggest potential hurdle IMO), set up a system wide configuration file (to be fair, one for each network stack you'll be using; in my case mTCP and WATTCP), point to it with some environment variable in AUTOEXEC and run the network software. It brings a smile though that I occasionally have to renew my DHCP lease manually.
