I want to add the option of automatic port forwarding (NAT Traversal) to an application.

I know this can be done using UPnP (specifically the part that communicates with the device presenting itself as an IGD – Internet Gateway Device).

I need to be able to test this port forwarding feature while developing it. And whatever big router system company traffic is routered over

  • Doesn’t provide UPnP.

  • Wouldn’t want me messing around with it while it’s in live service.

Does anyone know of any software that acts as or emulates a UPnP compatible router?

  1. You could use Windows Firewall / Internet Connection Sharing, which supports UPnp by default. Just setup another machine, with Internet Connection Sharing activated, and you will have a UPnp router.

    Also, you could check the UPnp forum for more information here.

    Later edit:

    You could also try setting up a linux/unix firwall with igd activated.

    Here is a forum post for ubuntu.

    And there is a miniUPnp project too.
