Access a PC behind NAT

Hi,

I am trying to make a desktop sharing application (like teamviewer) in
.NET framework 2.0, i was wondering if this is possible to connect a
pc behind NAT without port forwarding? The other option i can think of
is creating a tunnel between two pcs but i am unable to make a vpn
connection through command line i found a vbscript though which does
the work but thats not the best way of doing it, the created
connection could be dialed using rasdial command.

Is there any other way of connecting a pc behind NAT?

P.S. There are WCF(Windows Communication Foundation) and WDS (Windows
Desktop Sharing) for framework 3.5 but i am looking for a solution in
2.0.

Regards,

Ahmed Khalid

Dim objShell, sName, sHost
Set objShell = WScript.CreateObject("WScript.Shell")


sName = "COMPANY NAME"
sHost = "IP ADDRESS OR HOST NAME"


With objShell
        .Run "Control ncpa.cpl"
        wscript.sleep 2000
        .AppActivate "Network Connections"
        wscript.sleep 1000
        .SendKeys "%FN"
        wscript.sleep 1000
        .SendKeys "%N"
        wscript.sleep 1000
        .SendKeys "%ON"
        wscript.sleep 1000
        .SendKeys "%VN"
        wscript.sleep 1000
        .SendKeys "%A" & sName & "%N"
        wscript.sleep 1000
        .SendKeys "%DN"
        wscript.sleep 1000
        .SendKeys "%H" & sHost & "%N"
        wscript.sleep 1000
        .SendKeys "%AN"
        wscript.sleep 1000
        .SendKeys "%S"
        wscript.sleep 1000
        .SendKeys "{TAB}{TAB}~"
        wscript.sleep 1000
        .SendKeys "{ESC}"
        ' .AppActivate "Connect " + sName
        ' .SendKeys "%{F4}"
