    Port forwarding

    I know it is possible under most unixes(if not all), but can I have a certain port get forwarded to another Ip at a specific port in WindowsNT ?

    Its for our work email server. I really need to change the setup and put it behind our firewall. Currently the firewall is on the same box.

    Re: Port forwarding

    Let me see if I can remember this after using FreeBSD for so long. Are you using iptables? If so, try this:

    iptables -t nat -A PREROUTING -p tcp --dport 23 --to-destination 192.168.0.2 -j DNAT

    I hope I got that right. I couldn't remember what port mail goes on so you'll definately have to change the 23.

    Re: Port forwarding

    thats not what i meant... i knowhow to do it in linux but need to know how in nt. i am a unix guy, not an mcse (cert in evilness). i cant talk my it manager into a linux solution ... yet. ill break him eventually

    anyway in the meantime i need to make the godawful nt servers do the task. i need to make the firewall+proxy+exchange box into 2 boxes (firewall+proxy ; exchange) for security and ease of administration. Since exchange needs to be bound to a specific ip, i need the firewall to forward all smtp packets to that box. linux and unix i know. nt i dont (as well)

    I used to know NT but it has partly faded away. I believe it's in services though. Look for something in services in the control panel that would be relevant.

    Routing service.

    You might need the resouce pack.
