the HNetCfg com-api has all the necessary stuff in it to open and query upnp
devices.

Subject: [DUG] UPnP port forwarding

 

I'm increasingly being asked for help from my users for configuring port
forwarding in their routers.  My software has a couple of servers which need
to be accessed from the outside world if they wish to use some features.

 

I've heard UPnP will do this for them, and wondering if there is a simple
function someone has written for Delphi (D7) that can check if a specific
port number is already being forwarded and if not forward it.

 

Or otherwise a freeware app which can be run on a workstation to configure
any UPnP router.

 

Cheers,

Ross.
