Plex Media Server and 5G Modem

[Confused41]

Just changed over to a Telstra 5G modem (AW1000) and struggling now to connect to my Plex media server from outside the network.

Not sure if it's related to the modem or the update to Norton's VPN that happened recently.

Has anyone else have a similar problem?

The Telstra Home 5G service does not support servers. There is no public IPv4  IP address and the modem have there port forwarding disabled setttings disabled when in 4G/ 5G mode You could try turning on UPNP, (Network > UPNP IGD), which if working opens the required ports. I doubt that you will be able to connect to server even with UPNP turned on.
