Well, my published SSH Server is a SecureNAT client, I actually also have a Web Server published on the same machine and it works fine. The machine is a Debian 3.1 Linux distribution running Apache and a SSH Free Server. I've been looking through the ISA logs but haven't been able to find something meaningful. What would you do if you were in my shoes? Perhaps it is simpler that I think and your hint may help me to figure out a starting path to fix the problem. Thanks a lot for your help Regards, Wilmar Perez
