Got a trucking company that uses a hosted AS/400. The software runs on Port 23. I've set a group rule for Port 23 to be passed through but I'm still getting an intermintant disconnect with the software. Software company tells me it has to be a firewall (Edgemax Lite) issue. The old firewall was a Sonicwall, however previous IT didn't divuldge any of the usernames and passwords for me to cross reference with.
Any ideas?
