What is that FQDN resolving to? Have you tried using an IP address instead (both with telnet and in your rule)? Cordially yours, Jerry G.

Unless you are using a telnet command like "telnet <servername> 25" (at least in Windows) which will then use port 25. Mark -----Original Message----- From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Dan Crain Sent: Wednesday, September 26, 2007 7:18 AM To: isalist@xxxxxxxxxxxxx Subject: [isalist] Telnet question http://www.ISAserver.org ------------------------------------------------------- Simple question for the pros... I'm running ISA 2004. Does it automatically block a telnet session. I'm having an issue connecting to this one particular domain with my exchange server and needed to do a telnet session with it but can't get connected with it inside the firewall. Port 25 is open on the firewall and from home I can telnet to my server and the offending server. Do I have something configured wrong on the firewall? Let me know what you think.
