Hi PasTim, I find that the position of the INPUT rule in iptables that refers to the ipset upnp, does not seem to matter. What does matter however is the position of the OUTPUT rule - still don't know why. I am also using a timeout for the set of 6 seconds now which seems to be working better. The one thing I would like to do however is have the set expire immediately after an SSDP Notify packet is received; there is no reason to keep the port open at that point! In other words, cause an immediate timeout. I don't know how to do that yet. Note: Using Wireshark to watch the communication between LMS/UPnPBridge and my mediarenderer, BubbleUPnP, I have noticed a couple of things: 1. Sometimes it takes up to 8 seconds for BubbleUPnP to send the NOTIFY response back to UPnPBridge after it sends a SSDP M-Search broadcast! That is not good; it should be done in 1 second, so if we use a timeout of 3 seconds, set in ipset, we are going to have an issue right there. 2. I see that when BubbleUPnP sends it's NOTIFY response, it might repeat it as many 100 times! Ouch again. 3. I see that the server sends 4 SSDP M-Search messages approximately every 20 seconds, maybe BubbleUPnp I trying to generate responses to all of these broadcasts. -Ron *Living Room:* SB Touch + DIY PSU > CI Audio VDA.2 DAC + VAC.1 PSU > VRX.1 cables > Emotiva XSP-1 Gen 2 preamp + XPA-DR2 amp > Blue Jeans cables > B&W 804 speakers *Laptop:* System76 Galago + Ubuntu 16.04 + Squeezelite + Material Skin > ifi USB iSilencer > Audirect Beam DAC > Senn IE 80 earbuds *Bedroom:* Android Phone + SB Player + Squeeze Ctrl > Bluetooth > Bose SoundLink Revolve *Server:* Puget Systems Serenity + Ubuntu 18.04 + LMS 7.9.2 *Music:* Personal FLAC, Radio Paradise FLAC, Qobuz, Spotify ------------------------------------------------------------------------ Ron F.'s Profile: http://forums.slimdevices.com/member.php?userid=5616 View this thread: http://forums.slimdevices.com/showthread.php?t=103728 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/plugins
