Default How to connect from localhost-router-Internet-router-localhost Port 3456?

Hi
Each Router has a menu to perform Port Forwarding (it might be called
differently on your specific Router).
You simply indicate in this menu that you want to open Port xxx toward the
computer with a Local IP of 192.168.xx.xx (If your LAN IPs tend to shift
assign to the computer in question a static IP).
In general, http://www.ezlan.net/routers1.html

Assume I have an successful working in-house LAN with a router which works
as well as gateway to the internet.

Now I want to test how a client on my local computer works with a server
on my local computer.

When I connect both directly on my machine then everything works fine.

However I want to find out if they cooperate as well if they are connected
through the Internet.
In such a case possible difficulties regarding Firewall, NAT port
forwarding, DNS lookup
and others would be detected.

How can a simulate such an routing over the Internet? How can I force my
local computer
not to take the easy, direct way but to redirect all TCP/IP packets
through the internet?

Using a Proy somewhere in the world would not work because proxies do only
work for port 80
and http protocol.

How can I achieve a similar routing for lets say communication over port
3456?

Connect to another machine out in the internet using VPN. Use the VPN
connection to control the remote computer (eg Remote Desktop
Connection) to simulate one end of your communications and use your
local computer to simulate the other end.

HTH,

in summary on you local area network, you would like to access to a PC
which is again on the same LAN using Routers external IP right?
i have the same problem, any help will be appriciated

your router should support "NAT loopback", note that this feature is
not supported by most of the home routers
