do you want sort of upnp support?
you can get it as a script.
Download the attached utility, named MiniUPnPc (by
Thomas BERNARD).
Unzip it and put it somewhere accessible, like C:\windows
Then press ALT+F6 and paste this
[+server start]
{.exec|upnpc.exe -r %port% tcp|out=#X|timeout=10.}
{.add to log|UPNP: {.if|{.pos|is redirected|{.^#X.}.}|ok|failed.}.}
to test it, switch off/on the server. You'll get an output in the log panel.
