UPnP Proxy : I am developing a gateway for UPnP devices from last week to control the remote devices over the Internet.

I have started to write the code directly, but I am considering about the system structure because I am on business trip this week and I have no powerful PCs to develop.

Basically, I will develop two proxy modules for SSDP and HTTP including SOAP. To transfer the HTTP request, I have to change the request data which are related to the IP and the port such as the HOST header. I am considering how to complete the change more easily now.

Hello,

I stumbled upon your suggestion to bridge two UPnP Lans in to one single. I made a similar approach but at the application layer instead of in the networking layer. I used the OSGi Platform an the Felix/Apache (Domoware) UPnP Base Driver. The tunnel uses SOAP. It was targeted for J2ME CDC profile, and so I back ported both the base driver as your UPnP stack, since there are some java 1.4 constructs. The backport works on PDA's running IBM's J9 (Pocket PC - Win CE), etc...

Hi,

Is it possible to use this software to automatically create a UPnP port on a UPnP-enabled router for a server running on one of the LAN computers, such as an Apache web server?

Kind regards,

Hi,

Do you want to development about UPnP gateway devices ?

You don't have to use the proxy if you want only to set the port mapping.

Please check the following specification about UPnP/GW.

Hi Nico,

I agree with you that the easiest way to create an UPnP Proxy is by mean of the the UPnP Base Driver over OSGi.
