Here is my problem. I configure SC with only one HOST entry in the Helpdesk file, and everything works fine.
I have two PC's running viewer in listen mode on different ports. My router is configured to forward to the correct PC based on the port. But, when I add a second HOST entry nothing works anymore. I can't connect to either PC.
Has anyone else had this problem?
Thanks
