Hi Brian, there's several possibility. Let's assume the other end doesn't have a firewall, Try to trace route and ping the target host. If it's ok, then it's possibility that the target host has some sort of host filtering configured to block out unauthorised ip or the telnet service is not started. If there's a firewall, check with the other end to see if it's opened. tks.

Also running Trend Micro Interscan viruswall as a CVP server on the same server. Private internal network connecting to internet via DSL. Internal addresses are NATed. HTTP and FTP connections work fine. Problem is client machines on internal network need to be able to telnet to a law library service on the internet for research. When I try to telnet from the client machine to either the internet service or directly to the firewall, the telnet session never opens. Just get a "Could not open a connection to 'ip address of firewall'". Firewall log shows a telnet session accepted but nothing further. I do have a rule with source any, destination any or firewall, service telnet, accept. What piece am I missing? Thank you for any help.
