Secure Ports

This is a great site:

There are no spaces in the URL.
Hope this helps.

www.iana.org has all the data you'd ever want (and more)...but it can be difficult to wade through. Beware of rcf1700 as this is a very outdated form now.

The best site I know of as a quick reference for TCP/IP related ports is:

http://www.iss.net/security_center/advice/Exploits/Ports/

(delete any spaces in the URL).

Good luck!

these are the best two refferences for tcp/ip ports. If you wan to allow vpn only there are two ports that you need to open. 1723 and port 47 (gre). these are the only two you will need for vpn. Hope this puts you on the right track

You should check out Microsoft's Security Operations Guide for Windows 2000 Server.

Also, the SANS institute has a very good Step by Step guide for securing Windows 2000. You can find it here:

http://store.sans.org/store_item.php?item=22

It isn't free but you can order a hard copy for $49.00. I think you will find it money well spent.
