I reran the telnet test as when I did it the first time I did not put the port number 3493 at the end. [telnet 192.168.1.xxx 3493] This time telenet from 236 to 235 worked, however telnet from 235 to 236 did not. Here are the messages: *From 236 to 235:* *Trying 192.168.1.235* *Connected to 192.168.1.235* *Escape character is '^]'.* After between 10-60 seconds this message is displayed: *Connection closed by foreign host.* *From 235 to 236:* *Trying 192.168.1.236* *telnet: Unable to connect to remote host: Connection refused.* Wolfy, thanks for the direct connect offer; much appreciated. I'll try to contact you per your instructions. -- Fredericksburg, VA -------------- next part -------------- An HTML attachment was scrubbed...
