    I have a feeling it is a double nat issue. Is your modem also a firewall?

     

    I like to use

    to test for open ports. Is it actually open?

    It doesn't appear to be open externally when I scan for it.

    Here is the port routing rule in the modem:

    The redacted address is my static IP.

    The modem appliance does have an onboard firewall, but the settings are such that it is disabled (though you can't actually turn it off):

    It seems like everything is in order. I can't figure out why I can't make the handshake. Any ideas appreciated. :)

    If you open a port (any tcp port) can you access it externally?

    I have a workaround I’m doing to connect my parents house to my network. The have “internet” but it is a provided that is basically cellular, but not. They receive internet wirelessly. Their modem allows you to expose ports, but it is a double nat situation so it is actually not exposed. They could do port forward but it cost an additional $20 per month per port. Wonder if that is your situation? I have been able to get it to work with Wireguard, but it is all terminal work and not accessible via the UI.
