[solved] upnp problem with second WLAN Router/Subnet

[elgonzo]

Hello,
I have a new tablet-PC with android, and i want to use it to connect with "UPnPlay"-App to the TwonkyServer.
There is no problem to access twonky server (192.168.1.127) with my WD-HD Live in the same LAN (192.168.1.x)
I have an extra WLAN Router (Siemens SE551) in my living room, because my WLAN-Router (D-Link Dir-665 - access to the internet) is to far away.
So configured the LAN-Port of SE551 with LAN-IP 192.168.1.128 (way to Internet WLAN Router) and another Subnet for his own connects and WLAN 192.168.2.x.
But if i want to connect over SE551 to twonkyServer, no server is found.
If i connect direct through D-Link, the twonkyServer is found.

I tried to configure "Port triggering" on SE551 (TCP 2869 UDP 1900), but there was no effect.
A connection with an SSH-Client to TwonkyServer is possible.

So what's wrong, what can i do?
Is it a problem of the SE551 or can i configure TwonkyServer to allow another Subnet (192.168.2.x) ?

I could be wrong about the following explanation
For Ex: Bonjour, UPNP, and others
As I understand it, most if not all types of services that rely on broadcasts announcers and listeners
do this by attaching to the multicast group,
which will only work on one subnet, for the most part, without special configuration that some allow for
the clients also listen to this multicast group to know what is available to talk to
after that the actual conection is then based on the ip of the server it wants to talk to

Theoretically
You could configure a router to pass packets bound for the multicast group
possibly 224.0.0.251 or possibly 239.255.255.250
between your two subnets, assuming you don’t have NAT involved on the wifi router

But, to make life simpler, this does work
I would just use the wifi router as an access point
and bridge it to your network by just simply not using the wan port
and connecting a lan port to a lan port on the main router
make sure you turn off dhcp on the wifi router and change its ip to an ip on the main network

I do this now myself, I have 2 cisco e4200 (routers) being used an access points
to my dlink dgl-4500
with no broadcast or multicast issues on upnp, bonjour, airplay, etc.

In a nutshell try and configure your equipment and routers to work off of only one network 192.168.1.x

Thank you very much!
The simplest way was the best solution: Using the LAN-Port to bridge to my network.
Now i can watch all multimedia of my media server!

Excellent!
