I dont know if OS3.5 does, but OS3.9 has Genesis (tcp/ip stack). I know most people seem to prefer MiamiDX, but Ive always had more luck with Genesis (perhaps just because Im more familiar with it). There's also the new Roadshow and a free demo is available for that too.
You'll need cross-over cable by the way unless the gateway nic is 1Gb or greater.
