OpenVPN + DNS in VPN network only

VPN subnet: 10.70.255.0/24 VPN services subnet: 10.70.254.0/24

docker network create --driver bridge --subnet 10.70.254.0/24 myvpn-net

Setting up the routing between networks

Either edit the config/ovpn/ovpn_env.sh or run a startup script

iptables -t nat -A POSTROUTING -s 10.70.255.0/24 -d 10.70.254.0/24 -o eth0 -j MASQUERADE
iptables -t nat -A POSTROUTING -d 10.70.255.0/24 -a 10.70.254.0/24 -o tun0 -j MASQUERADE

Checks

# prints routing table
ip route

# add static route to client or server
# the following line adds routing to the local network of the host via docker bridge gw
ip route add 192.168.10.0/24 via 10.70.254.1 dev tun0
