I'm running a WireGuard server to try and forward the Host's IP to a child container using gluetun.

I'm testing with my VPN on my VPS with WHOAMI which will later be an email server which requires
the HOST IP for CNAME, A, AAAA, etc records.

  root@server:~/wireguard/wireguard_conf/peer1# cat peer1.conf
