there is good and accurate documentation on this in the nt 3.51 res. kit 
update 1...
however the nic and ras or isdn ip do not have to be on different subnets as 
documented.. you can have your ras or isdn say be x.x.x.1 and your nic be 
x.x.x.10 and set the two registry parameters ipenablerouter and 
disableothersrcpackets as documented... if they are on the same subnet (ie 
very common to have the whole class C) you simply need to add a static route 
for every workstation in your local network on the nt box... in addition each 
local machine should have the nt box as the default gateway and there should 
be NO default gateway on the nt nic card settup... as I said the docs are 
pretty good..
