I appreciate that ProtonVPN offers ipv6 support for their linux client, however my home internet (Tmobile) doesn’t work at all when ipv6 is turned on

So I have to turn it off via settings:

IPv6 Tunnels IPv6 traffic through the VPN. Can enhance compatibility with IPv6 networks.

My question is, does turning it off post any privacy risk, e.g. IPv6 leak? or compatibility issues in general?

Thanks!

    Proton runs IPv6 6 through a nat and properly blocks incoming connections so that is not a problem here. Also while it isn’t the default on all routers it is still entirely possible for the router to have a firewall on IPv6 connections so no incoming connections can connect to your devices unless you have allowed it.

      I am not super knowledgeable about networking

      But reading IPv6 routing rules led me to turn if off outright rather than be precise

        Fwiw, ipv6 is not insecure by default. Most firewalls, if not all, block incoming connections by default and Nat is not security.

        That and ipv6 privacy addresses nullify privacy and security concerns.
