Smart 5G Hub 3 - Passthrough Mode Not Displaying WAN IP but a LAN IP.

TrickyT · ‎06-01-2025

Just got my Smart 5G Hub 3 and set it up in passthrough mode.

I was expecting to see my WAN IP displayed in my Unifi setup, but it is displaying 192.0.0.1 instead of the WAN IP address 31.xx.xx.x

The cable is plugged into the LAN/WAN port on the Smart 5G Hub 3 and I know that the IP has been changed as I used 192.168.1.1 to log onto it and set it to passthrough mode.

Is it just a bug in the firmware?

Where is the cable plugged in at the Unifi end? What Unifi model is it anyway?

The cable is plugged from the lan/wan port on the 5G Hub, to the WAN (port 9) of the UDM SE.

Everything works, just not reporting the external IP address.

Apparently this is the expected result as EE implement CGNAT.

Can anyone tell me which Subnet I should be using in pass thought mode?

The default was set to Force 24 subnet, is this correct?
