Hi I am having really weird telnet problems. I am trying to telnet into my backoffice server (isa server) that is running a d3 database software which was an old pick software. when we are in house and we do a telnet to the internal ip number, we connect to the d3 database software with no problems. If I try to connect from the outside, nothing!! The strange part, is if I start the Microsoft Telnet server and try to connect by telnet from the outside, I can connect to the Microsoft telnet server. This shows me that port 23 is open and the firewall is letting it in. But why can I not connect to the D3 server?? I checked and it is listening on port 23. Any Ideas??? Thanks Dale
