What is the model of your equipment?

It’s a GL-AX1800 router

Hi mif:

Is your vpn configured with ipv6?If yes, please delete IPV6.

It should use dynamic ipv6 addresses.

If it’s convenient, Please send me the vpn configuration to check.

I have this in the configuration file:

ignore-unknown-option ifconfig-ipv6
ifconfig-ipv6 fd15:53b6:dead::2/64 fd15:53b6:dead::1
redirect-gateway ipv6
block-ipv6

Also I have IPV6 disalbed in the Network => IPv6 page.
What should I do in this case?

As I understand, inability to use IPv6 can lead to my real location will be available to some services. What If I need to use IPv6?

What if you enable it?
