Three 5G hub (Huawei H112-370) and Port Forwarding?

I just started using Three 5G days ago. Everything seems fine with speed and coverage of wifi around the house.

I'm just getting mad trying to understand if the router REALLY supports port forwarding of if it is ThreeUK that is blocking it somehow.

I'm trying with a very simple setup...my local machine with a web server (so Port 80, easy peasy).

I added it to the "virtual servers" list, port 80 and the IP of my machine, tried to reach it from outside via direct IP address: no results

I also tried to add my local machine to the DMZ (doesn't make sense though): same no result

Tried to chat to ThreeUK and they say the hub DOES support port forwarding but they don't give tech support on it. Interesting and useless answer.

Any idea?

Btw...also DynDns seems not to update my IP address to the hostname.

Thanks.

I am quite sure they do CGNAT so you share the IP with others

When you say Three 5G, is that Three UK (mobile), or Three Broadband (ex UK Broadband Ltd brand called Relish, but currently just renamed to Three Broadband)?

If its Three Broadband, I'm not sure what APN's they use, or if their APN gives you a public external IP (if it doesn't, then it's CGNAT, as mentioned above). What are the first 2 octets of the IP?

If its Three UK (mobile) then switching to the 3internet APN (or setting that up) should give you a public external IP that can be port forwarded easily.

I'm talking about Three Broadband. My IP is on 46.237.xxx.xxx

It's really annoying. Not vital but definitely upsetting also for Three's approach to customer service. Why enabling DMZ, DynDNS and Virtual Servers (port forwarding) if the whole thing is not publicly visible?

I didn't think before to do it, but pinging my IP address gives no response....and this I think confirms your CGNAT theory. I didn't know about CGNAT...and now I have few days to decide if to keep the service or not.

Any known workarounds? Thanks.

Wait for IPv6 - then not only will your router likely have its own public IP but each individual device on your network

You could rent an L2TP connection - that would give you a public IPv4 address over CGNAT:

If dealing with cgnat then your best option is to get an l2tp vpn from aaisp as suggested above, that will give you an IP that is public and will also likely work with Netflix etc.

I can vouch for the AAISP L2TP service - I've been using it for a couple of years. Not only does it give you static public IPv4 and IPv6 addresses, it means you can change between ISPs or mobile providers as you wish without your IP address changing (good for failover solutions).
