Hello Tommi,

Of course. The vast majority of the customers will never notice that they are behind a CGNAT. They won't even know what a CGNAT is. Of the small minority that knws about it, an even smaller minority will run stuff that requires a public address en they will complain.

Here all mobile is behind CGNAT. And no IPv6 on the mobile yet. So no servers.

Flat rate on the LTE or data cap?

Why does the LTE connection change?

If it works for you. ;-)

 TK> Exactly.

But I have not seen it yet here. You either get a public IPv4 or you don't. No extra payment.


Cheers, Michiel
