[BUG] Dual-stack IPv6 traffic is not dropped and therefore spoiling the true origin of packets

[ghost]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When I use this as a client on a dual-stack machine, my IPv4 traffic gets wrapped into WG tunnel and my IPv6 traffic doesn't. Since your container doesn't support IPv6 as of today, on the related interfaces it should not allow any IPv6 traffic to not spoil the origin of packets.

Expected Behavior

I expect that when I bring up a tunnel it hides my origin by blocking IPv6 on related interfaces.

Steps To Reproduce

Run a client on dual-stack machine then run IP tests in browserleaks.com. It is gonna say that by IPv4 means you are in XYZ country and by IPv6 means you are in ABC country.

Environment

Any IPv6 && WireGuard capable host with a browser.

CPU architecture

x86-64

Docker creation

docker compose up -d

Container logs

No logs.

did you configure your custom bridge to support ipv6? As you can see in our default conf, the static route sends ::/0 across the tunnel.
