Legacy0 — Mon, 02 Feb 2026 22:38:34 GMT

So I gave IPv6 a try but found I could not ping my router Zyxel FWA510 I get a IP ***** but every site I try to ping me fails even with firewall disabled...why is that?

thanks

[Mod edit: Removed specific IPv6 address for privacy. Your technical question about IPv6 connectivity issues is still clear and helpful!]

It's a limitation of EE's mobile network. The EE mobile network uses Carrier Grade NAT (CGNAT) resulting in a double NAT, which means that you don't get your own public IP address but share it with other users. So you can't be uniquely id'ed on the Net & therefore your LAN cannot be addressed from outside for unsolicited accesses. This is unlike fixed BB.

But this is IPv6 not IPv4 whats the point in IPv6 on mobile network if your not got to get the full IPv6? seems pointless to do IPv6.
