Add option to only route LAN traffic

[patrikdolsson]

I'm switching to a docker openvpn-server solution from the router solution (Asuswrt-merlin) I have used earlier to access my home network remotely. This server had the option to only route LAN traffic, internet traffic or both. As I only used this to access my home network I quite enjoyed the feature of only routing LAN traffic.

Is it possible to add an option to only route LAN traffic? Not sure if it's as simple as adding an environment variable or if it would require more information such as subnet and/or netmask. In any case I would like to see this feature. :)
