Why wouldn't this happen as an iptables rule?

If some AllowedIPs trick is working for you and you're using Python and the kernel version of Wireguard, check out [1], which will allow you to programmatically set up the interface.

FWIW, I'm not sure adding complication to AllowedIPs is the right approach, but adding it to a tool seems reasonable. Maybe it also makes sense to allow an IPset, but I'm haven't thought it through. My gut says routing prior to Wireguard is probably what you're looking for.

Also, since ISPs apply different censoring rules, sometimes my own servers are not reachable via the VPN (because the server’s ISP blocks the VPN, while my local ISP does not.)
