    I’ve had an ELK at home for a while, and recently had one installed at our Lake House which uses StarLink for internet.  The phone connection to Alarm Relay works, but we can not get the internet working as a backup.  We get the Ethernet trouble when it tries.  We spoke with Alarm Relay and they are convinced that StarLink is somehow blocking the connection.  But I can telnet to their IP address and Port so it sees it just fine, but of course drops the connection immediately.  We even spoke with an IT person there who claimed it was because StarLink does not allow port forwarding, which make no sense because you don’t need port forwarding to connect out from the local network.  I know that StarLink uses CGNAT so I don’t have a public IP address which is what I assumed was the issue, but there are many ISP’s which use CGNAT.  Anyone have a clue on what we can do, or how to debug this?
