Example
[ Homeserver VM ] [ Server VM ] Docker:Service A <--> Docker: OpenVPN Client <-------------> Docker: OpenVPN Server <--> Docker: Service B 172.111.1.2 10.8.0.2 172.1.4.3 172.1.4.5
How can service B communicate with Service A?
Server VM
ip route add 172.111.0.0/16 via 172.1.4.3 dev br-...openvpncontainer..
OpenVPN Server
iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE server.conf: route 172.111.0.0 255.255.0.0 clients/homeserver: iroute 172.111.0.0 255.255.0.0
