UPnP not working after traffic forwarding through server

blither · 12-30-2010, 11:49 PM

I have just recently switched my setup to have my server be in the middle of traffic and act as my new router while making my other routers just switches. However, after doing this I can no longer access my UPnP devices. They used to show up in my router but I am assuming either there is an issue with my iptables rules or that some how having my server run the dhcp and dns routing is messing with UPnP.

If anyone can think of a reason this isnt working that would be great.

Thank you.

Did your subnet change when you moved dhcp to the server? I would definitely check iptables to make sure the proper ports are open and the subnet is allowed. Also, have you confirmed that the UPnP devices are successfully obtaining an IP address from the new dhcp server?

The subnet should not have changed. The devices do have correct IPs.

Here is the diff for my ports on the internal network from mediatomb running and mediatomb not running.

Code:

10d9
< tcp        0      0 0.0.0.0:49152           0.0.0.0:*               LISTEN     
19d17
< tcp        0      0 192.168.1.7:49152       192.168.1.8:34198       TIME_WAIT  
37d34
< udp        0      0 0.0.0.0:1900            0.0.0.0:*                          
39d35
< udp        0      0 127.0.0.1:46071         0.0.0.0:*

For the time being I have turned back to my original setup with the system still not working. I am now relying on my wireless router to be my full router. But for some reason I cannot get UPnP to broadcast to other devices it is listening for connections.
