Hi. I want to route traffic over an OpenVPN client on the host to the guests, since for me this achieves the fastest speeds possible. Even though my network fully supports IPv6, and so does the remote OpenVPN server, all guest VMs have 100% packet loss with only IPv6 (IPv4 works as it should). I was able to use a bridge on the br0 interface to get both IPv4 and IPv6 working, but it doesn't route through the VPN client at all, and I'm not sure how to fix it (I just started learning about network bridging).
I don't know what information about my network setup to post, so ask if it's needed.

Code:
$ lspci -nnk | rg "Ethernet|igb"
05:00.0 Ethernet controller [0200]: Intel Corporation I211 Gigabit Network Connection [8086:1539] (rev 03)
