Hello,

Seems after last whonix update my old VPN VM begin leaking traffic. After investigation I found that it's because ipv6 primary connection to whonix-gw. I guess that whonix-gw now supporting ipv6. It leak traffic through ipv6 connection to whonix and ignore my default old ipv4 setup. "qvm-features VM ipv6 0" fixed this issue! But I'm not sure about all my others vpns and leaking with ipv6. How I must fix this at vpn setup (on load) to be 100% sure that it never happen again?

The Qubes-vpn-support / qubes-tunnel firewalls have had ipv6 anti-leak for some time now. Also, the scripted section of the Qubes vpn doc has had it as well when I added it last July. But it looks like the Network Manager section should be updated to also include it, since that section now suggests firewall settings.

FWIW, I'm not sure when Qubes started enabling ipv6 by default. I thought R4.0 was going to support ipv6 but leave it disabled by default?
