- OPNsense: Prefer source address

· Note: This post is about IPv6 addresses. I assume it works with legacy IP, too (untested).
Problem Before switching to a modem I had configured a static WAN address. I chose that address to be also used as WireGuard endpoint address. WireGuard has one major problem: You can’t configure the address it’s listening on. It relies on the underlying operating system to fill in the source address. And this can cause problems on a machine with multiple interfaces and addresses like an OPNsense firewall as you will see now.

[root@test ~]# ip link add dev wg0 type wireguard Error: Unknown device type. No, you didn’t do anything wrong! Yes, that’s the right way to install WireGuard on Arch! So why isn’t it working? The fix is pretty simple: Update your fucking system!
[root@test ~]# pacman -Syu :: Synchronizing package databases... core is up to date extra is up to date community is up to date :: Starting full system upgrade.
