router with NT

[Dominique THIRY]

Maybe a simple question: I have a NT box running NT4.0 workstation. IP forwarding is enabled on it. I have installed an NIC and an ISDN card (to connect to my Internet provider). Is it possible to use that NT box as a router between my firewall and the Internet ? May need additionnal software ?   Thanks, Dominique THIRY Systemat Luxembourg
