      My father-in-law uses the T-Mobile 5G Internet Gateway (Arcadyan KVD21) for internet access. I am wondering, whether there is are ways to work around the fact that T-Mobile won’t make bridge mode on that device available or the device is incapable of being configured that way. The problem is that I want to use a pfSense appliance downstream from the T-Mobile device and want to find a way around double-NAT.

        @DominikHoffmann while double nat is not really optimal.. More than likely you will not have any issues.. There are 1000's if not 10's of thousands of people that are behind double nat, shoot even triple without any issues at all..

        What are specially trying to do.. I am like 99.999% sure you can not port forward when using t-mobile 5g.. if that is what you were hoping to do.. They use CGnat I can almost promise you.. Also with that sort of connection - the IP being used prob changes all the time, etc..

        But if what you want to do is normal internet stuff, stream, surf, etc. etc.. you should have no issues..

          I just learned that the Verizon 5G internet gateway (an ARC-XCI55AX) can be placed in bridge mode (per an article in the Verizon knowledge base). I am now looking to find out, whether dynamic DNS is feasible with that. What you, @johnpoz, wrote about the IP address being very unstable, might apply for Verizon as well and would blow VPNning into such a network out of the water.

            @DominikHoffmann I find it highly unlikely that any of these 5G hotspot/internet things are providing a viable public IPv4 address that you could use for unsolicited inbound traffic..

            edit: hmmm well butter my butt and call me a biscuit ;)

            Maybe you can do it with the verizon 5g internet
