From receiving the item, I had an already working home office setup, all I needed was to put the sim in the new RUT, connect aerials and power on, I connect to the LAN port with my PC, I get an IP, i visit 192.168.1.1 and go through basic setup.
4g Connection is up, data only going out, no IN.
I have no NAT setup manually. I have open firewall completely until connection works.
Ping to 126.96.36.199 fails.
