Hi John, Not exactly. You can't use the same socket twice. A socket consists of: A transport protocol: UDP or TCP An IP address A port number So, if you use a socket for a Web listener, it looks like: TCP 222.222.222.1 80 If you use a socket for a FTP Server Publishing Rule, it looks like: TCP 222.222.222.1 21 Since these are not exactly the same, you can use the FTP Server Publishing Rule on the same IP address.

Yes, I have Tom's book http://www.ISAserver.org Tom, But not using the same public IP that has a listner setup for Web Publishing,,,,right? I was under the impressions that if a web listner is setup for a paticular public IP that you can NOT use that same IP in a Server Pub rule. Am I off track here?
