I do have mobile connection which is working fine when going to the internet. The router (WAN side) does have a private IP while it should be a public one.
What I want is that certain ports are open to the internet, for example port 1194 for openVPN.
The (LTE) modem is configured in QMI with mode NAT, but if I change this, to bridge would I be able to forward ports to an internal IP address? Or should I use passthrough ? In both cases a bridge MAC is asked, which MAC address should be used?
As it is now (NAT mode) UPnP does not work either.
Who can help me further?
