[App_rpt-users] How to prevent incoming connections

Hi, When I play the GB2RS news and ARnewsline audio files over my node, the playback is killed off by an incoming connection. How can I prevent an incoming connection during this time? I thought I could disable the node but of course this kills the Tx completely! Didnt want to do anything as drastic as take down ETH0 if I could help it as the node is on a remote hilltop. Any ideas would be greatly appreciated. Thanks, Matt G4RKY
