I have the same "issue" what Ports exactly TVHeadend needs for searching the TV Adpaters (SAT IP) ?
At this time i have UDP Ports from 40000 to 55000 open for the SAT IP Adapter, but can i define a specific Port ?
For the Adapters itself i can define a port but that is only when TVHeadend has located the whole TV Adapters.
If i restart TVHeadend and dont open the ports 40000 to 55000 no TVAdapter is found...
