We have used IP 10.3.0.80 which is a local IP from the main router IP Pool and
we have forwarded from the main router the 1723 port for the IP 10.3.0.80.
We have to route IP for internet access.
We have to add IP 0.0.0.0/0 in "Dst. Address:" box and your ISP gateway in "Gateway" box or you can simply add the interface where the main cable is plugged in.
