Fatal Error with Multihop. about qomui HOT 5 CLOSED

Disabling IPv6 will disable the IPv6 stack systemwide, so your System won't be able to handle IPv6 Connections at all. The firewall will block outgoing and incoming IPv6 and IPv4 packets that are not going through the OpenVPN/WireGuard tunnel. The latter option is preferred if you want to avoid IPv6 leaks.

Can you check if "/sbin/route" is available on your system? My notebook is running Antergos/KDE as well and double hop with Mullvad works fine there. Furthermore, Mullvad has changed its config recently. Reading your log, this doesn't seem to be an issue in your case, but I'd recommend to update to v0.8.0 anyway.

I should've clarified. I was using Mullvad as first hop and AirVPN server as connecting server. It took me hours to figure out it was AirVPN's IPv6 timing out when I chose to connect with ipv6 in the Provider Tab. If I connected with IPv4, IPv6 would leak. Weird thing is I can connect to AirVPN's IPv6 on their Eddie client perfectly fine and it was assigned. So, I disabled IPv6 on your app but that triggered Mullvad to run into an error because it was trying to assign an IPv6 address. Then I found that I had to disable IPv6 on Mullvad configs using this..

I have disabled IPv6, either systemwide or on the Tun/TAP interface, and OpenVPN exits out with a fatal error.

Edit the OpenVPN configuration and do the following changes

Replace proto udp with proto udp4 and proto tcp with proto tcp4
Add pull-filter ignore "route-ipv6"
Add pull-filter ignore "ifconfig-ipv6"

Be sure to check that there are no IPv6 leaks if you have IPv6 enabled on other interfaces on that system."

At the end, I was able to connect perfectly.

Yes, this is indeed an issue. That's why I don't recommend disabling ipv6. To prevent leaks, you should activate the firewall instead. Furthermore, you can't create a double-hop with AirVPN if you choose an ipv6 entry ip. The routing only works with ipv4.

What is the difference between Blocking IPv6 and activating firewall?
