VPN-Firewall discussions in Whonix forums

How exactly did you verify this? Did you open a browser on the GW? Did you know FireFox resolves its own DNS queries?

The only reliable way to test leaks is to run tcpdump and supply a log here.

This is not related to Whonix. There is no Whonix-Gateway (GW) involved.
It’s about VPN-Firewall on a Debian jessie host, right?

This is a common problem that has to with how VPN software is designed. It fails open unless you script your firewall to block outgoing connections when the VPN fails - failing closed.

This has nothing to do with Whonix. please lookup general linux support forums.

That’s what he is using - VPN-Firewall - Leak Protection (Fail Safe
Mechanism) for (Open)VPN.

VPN-Firewall was created by me. VPN-Firewall is documented in Whonix wiki.

Although not a part of Whonix anonymous operating system.

A small mess up on my side, perhaps.

So from a user’s point of view it’s not terribly wrong to ask about it here.

Oh so this was meant for use outside Whonix. Didn’t know that.

I thought the OP was complaining about a leak on the host while running it on the GW. Nevermind.
