Static routing rules

Many users like me, have a VPN server inside our network, we can already open ports to make the connection from the internet but we cannot send traffic from our VPN to the local network (unless we use NAT, which is not a good option since we cannot initiate connections the other way around).

Another case is for MPLS or other types of private networking that is transparent to the user and their computer (like a VPN with AWS or other clouds).

Others have multiple networks (VLAN or physically), so the need for a simple Static route is needed to achieve this.

Please implement this.
