I'm seeing this problem as well. Is there a way to kill network connectivity during reconnections to avoid leaks?

mike-lloyd03 commented 1 year ago

It seems this is exactly what the kill switch feature is intended to do. Is there any way to implement this here?

mike-lloyd03 commented 1 year ago

Looks like this has already been addressed here.

So what's the go-to workaround for this? Having traffic leaks for a VPN is really bad.

I guess we just have to use a single server WireGuard container instead?

Avamander commented 1 year ago

@paya-cz You can create post-up and pre-down iptables rules for it in wireguard's config.
