Dynamic IP address

[Prydd21]

I need a public IP address, how do I go about this please?

Yep, by description I got public ip and I configure port forwarding  but port forwarding does not work from router network,  you need to test it from other network,  e.g. your mobile internet from phone.

check your apn on your router is using "3internet", its non cgnat, it works fine and is publicly routable.

plesse can you screenshot the relevant router pages so I can copy it word for word?

cheers

Which router are you using, I have tried this on both Huawei cpe pro 2, and Zte mu5001 (non three) and port forwarding works for me, remote access to cctv, and open nat on xbox etc.

I think the router APN pages will be similar so if you could screenshot your APN page I would be obliged.

cheers

I haven't got access to it currently, but from memory on my zte router, 
disconnect first from the main router page, then in settings go to apn,

create a manual apn, put in 3internet as the address and name it, nothing needed in the authentication boxes.

make sure it uses ipv4 only, not ipv6 or ipv4/6.

then save it and make sure the right apn is selected the new one you just created and go back to the main router page and click connect.

Out of curiosity - why does it have to be IPv4 only? Indeed dual stack puts the IPv5 behind CGNAT - but wondering if this is a bug or by design and whether it will be changed?

Thanks for your reply.

I’ve already tried what you have said.

that’s why I asked if you can screenshot the exact page and I can copy it word For word.

that rules out any errors.

im not in a rush so when you have got access will do.

cheers

Hi All,

Just to add something here - I came across this conversation while having the same issue myself - My Public IP (188.30.x.x) was showing as different to the one shown in the router -  (192.0.0.x). I checked the advice listed here - and saw that the default profile was set to "3internet" already - but it was said to create a new one - which I did. Literally all that needs to be set is changing the mode to "Manual" and adding "3Internet" to the APN section, then save the new profile - this is identical to the default, however, once set, I could see that my WAN IP in the Web GUI now shows as 188.30.x.x. This solved my issue, I hope it can maybe help others. 

For others wanting to set this, log into your ZTE Router - and in the Blue Network Map, select "Settings" under "5G" (or 4G+ / 4G etc, depending on your connection) - in the "My Router" Section. On the next Page select "APN". On the next Page, change the Mode to "Manual", then "Add New" - this creates a new, blank profile. Give the profile a name - I used "CGNAT Test" and "3internet" in the APN section. Everything else can be left blank. Select "Apply" to save it. You just need to make sure that the "Profile" section shows your new profile - I selected "Set as Default" to make sure it always uses this profile. 

Once completed, I could see my WAN IP changed to the correct one, and not a CGNAT address (CGNAT SHOULD be between 100.64.0.0 and 100.127.255.255, but maybe Three are using ones outside this scope for some reason - having 192.0.0.x is a big indicator it is a CGNAT address).

I hope this helps other users.

Thanks,
