My router APN with this SIM in is just 3internet, CGNAT off.
My phone is three.co.uk, CGNAT on !! What was that I said earlier
That is what I remembered! Thanks. Not sure if phone contracts are allowed to use the 3internet APN it may be only available to data contracts. So when using a phone SIM in a router (or a phone tethered to a router) is going to give CGNAT....which will make some online gaming impossible.
Not a problem for everyone, but one to be aware of if switching from traditional broadband.
There just won't be enough IPv4 addresses left for everyone with a 3 phone to have a public IP. I suspect a lot less data contracts.
OK, I'm now thoroughly confused about this CGNAT question in respect of my own connection
Using the tbb IP Address checker the phone has one address. With wifi tethering it keeps that but three devices connected have identical IP addresses to each other but different from the phone.
If I USB-tether the phone to the ASUS router the same applies, with two of them wireless and one ethernet.
I do not see anywhere a WAN IP Address for the router in that setup
So is my connection on CGNAT or not?
My broadband basic info/help site - www.robertos.me.uk.
Domains, site and mail hosting - Tsohost
Connection - Three 4G, tbb tests 35-45Mpbs down, 9-15 up.
If you never think of anything off the wall, you'll never think of anything original.
