Port config problem with WiModem

[admin]

You should be able to "call" your BBS locally, using just WiModem's IP address and port. For accessing the BBS outside of your local network (like via another computer somewhere else, your phone on cellular data, etc.) You are going to need to setup a virtual IP. I use NO-IP myself (www.noip.com) for doing this.

Verify first that you can connect locally by using some device that has access with a terminal program on the same network.
