Help with Upnp over two router

[astrosheen]

So currently I have a crappy router/modem in the garage that links directly to a D-link dir 868L in the study in the center of the house. The dlink gives the wifi for the house and connects a PC which is used as a media PC/home computer. Coming off the crappy router I have a raspberry pi running xbmc. What I would like is to be able to get the raspberry pi to connect to the media PC using Upnp but it currently will only work with both the media PC and raspberry pi on the same router is there anyway the upnp could be port fowarded or the like for this to work.

You need to go into the settings for your "Crappy Router/Modem" and find the setting for bridge mode, than connect everything to the DLink it's no use to have things connected seperately like that. I think you should have it setup like the following:

 

Incoming Connection (ADSL) --> Crappy router / modem set to bridge mode --> DLink DIR-868L --> Wifi Devices, Media PC, Other Wired Devices, Raspberry Pi + Switch

 

Also what ISP do you have and does your Crappy Router / Modem run propietary firmware? If you can't find the bridge mode setting try contacting your ISP and asking them to enable that for you.

 

In order for this to work you need to have everything running off of ONE router / modem. Hope this works for you, this is my personal experience with Upnp and Windows Server 2012's web interface needing to work.

 

EDIT:

Forgot to add, if your DIR-868L doesn't have enough Ethernet ports, invest in a nice switch or try running most things off of the existing switch you detailed in your diagram.

the issue is the raspberry pi must be connected to the crappy router due to the way the house is wired

You could run the Dlink as an AP instead of as a router, if you can accept the crappy router doing your DHCP and DNS. Then all your devices would be on a single network.

 

As for forwarding UPnP, I believe you can forward the discovery packets with the right configuration, but I wouldn't expect that to be something you can do from the interface of either router. And that wouldn't help the devices actually connect to each other once they discover each other either.
