The motivation for me to write D42880 was the same as yours and in fact it is perfectly doable with the current integration. In my case I have the following setup: A script /etc/start_if.wg0 which contains: --- #!/bin/sh /usr/bin/wg setconf $1 /usr/local/etc/wireguard/$1.conf --- Note that in this configuration one need to not have the Address in the configuration unlike regular wireguard. the rest is handled in rc.conf cloned_interface=wg0 ifconfig_wg0="inet ..." static_routes="zone0:wg0" route_zone0="-inet ..... -interface wg0" This gives me a wireguard interface pretty early in the boot process. and simple configuration without the requirement of a single package. Note that if I create a wg1 I just need a symlink: /etc/start_if.wg0 -> /etc/start_if.wg0 Best regards, Bapt
