@selfhosted Have a commerical @wireguard vpn on my server. The problem i have is that if i use a docker, it does use the vpn interface with iptables, but if that goes down, the docker still goes through without the vpn interface. I have looked at iptables, but docker makes it own, and bit of a minefield. Any ideas? Thanks

IMO the best way to ensure that traffic always goes through a VPN is to use network namespaces. The wireguard website has an article describing the process. In a nutshell, you create a dedicated namespace to put the physical interface in, create the wireguard interface in that namespace, then move the wireguard interface to the root ("normal") namespace. That way the only way to get traffic out without the VPN is to run a program in that dedicated namespace.
