I have multiple facilities with a Sierra Wireless Modem/Router with ports forwarded to an Ubuntu Edge Computer (443 web interface, 22 SSH, etc.)
Recently, we're seeing strange behavior where the forwarded web interface loads extremely slowly, or won't load at all. The web interface to the modem itself has similar problems.
However, the SSH port forwarded to Ubuntu is working normally. And, even stranger, if I open SSH tunnels to the web interfaces instead of going through the port forwards they load at normal speed.
Don't understand what's happening here, or how to resolve. Seems like if the router was overwhelmed then we should be seeing SSH tunnel issues as well?
