Outgoing wireguard when connected to Nighthawk M1 blocked

[molotch]

I've been unable to establish a wireguard connection when I'm connected to my Nighthawk M1 mobile router. The wireguard connection works flawlessly when I hotspot through my phone (same provider as the mobile network on the M1).

Have anyone else had this problem or know how to solve it? I'm on firmware version NTG9X50C_12.06.39.00

Maybe run a good port scanner such as nmap against it and see if the Wireguard ports are blocked?
