Flole There is no need to forward any ports if you don't do NAT. You just need to make sure the traffic is routed and not blocked. If you're doing NAT (which doesn't make any sense and makes things more complicated) you should forward all UDP ports or specify the ports in Tvheadend. Adding that option is necessary if you don't let UPNP go through your router.
Oliver Greling UPnP is activated. Believe me, I tried A LOT ;) That's why I am trying to get a clean line in thinking about this and solving the isssue... :/ What about the "satip_xml..." thing?
Flole As I said: If you're indeed routing UPnP between the subnets then the satip_xml option is not needed.
Oliver Greling Well, I now deleted the satip_xml option - now i cannot see the tuners anymore. And all UPnP settings are on. Here is a screenshot from my gateway:
Flole That option doesn't say anything about Routing of UPnP, it just allows the Firewall/Gateway to be configured with UPnP. But this is probably not the right place for support with configuring your gateway, the manufacturer or a specialized Forum is probably a better place to ask and get this kind of support.
Oliver Greling It's not about configuring my gateway, it's just about finding a solution in getting the BASIC idea of what to do - regardless of the gateway hardware...
Flole As I said: Disable NAT for that host, allow all UDP Traffic to go through from FritzBox to Tvheadend and add a static route. Specify the URL and don't care about UPnP. That's it. Now you just need to figure out how that is done on your firewall/router.
Flole Don't do NAT for traffic with the FritzBox as destination. The source address that reaches the FritzBox should still be the original IP address and not the address of the gateway.
Flole Have you disabled NAT for that host, allowed all UDP Traffic to go through from FritzBox to Tvheadend and added a static route? If you are missing one of those steps it won't work
