I have a VPN server which connected to the internet over eth0. And VPNetwork's device is as0t0/as0t1. I have a specified VPN Client which i want to reach it over internet over VPN Server's public Internet IP(x.x.x.x).
I want to reach VPN Client over 7777 port over Pure Internet, but it is behind the NAT. I want that: When i connect to the x.x.x.x:7777, it must be routed to the VPN Client's same port.
I have tried somethings using iptables. But didn't worked. Is it true way? If yes, what must i do exactly?
