Airtel Xstream Broadband has switched to CG Nat

[tatyasky]

@tatyasky Finally, I was able to get the ipv6 address in the router. But the internet doesn't work on that.
Seems the same mac cannot dial another PPPoE and hence, it was not connecting earlier. I had to use the same Ipv4 session. then I get IP but not the Gateway. If I just dial ipv6 (no IPv4), I get the gateway but still internet doesn't work. It's may be because I have public IPv4?

Dial PPPoE only on IPv4.
IPv6 will auto-connect on dual stack once successful IPv4 connection is made.

Very important is NOT to use SLAAC option.

To disable Windows 10/11 temporary IPv6 assignment run these commands one by one in elevated admin powershell

netsh interface ipv6 set globalrandomizeidentifiers=disabled

netsh interface ipv6 set privacystate=disabled

Reboot PC to get a static IPv6 address. You may also need to add firewall exception in TP-Link router if it has a IPv6 firewall.

finally working bridge mode and I am able to configure ipv6 too.
But not working on browser.

 

[tatyasky]

Have you tried ipconfig /flushdns command in elevated powershell?

@igloo how did you configure ipv6? Nokia ont or any other router on bridge?

I have sent mail for bridge mode.
Will ask them about ipv6 too now that I am on cgnat.
Can't do much on this router.
Everything is disabled.

Did u send the email few minutes before writing the comment here?. Also, you said bridge mode is working now, so did they call you or did u try to enable now and it worked?.
