Using opnsense as my router and apple music on wired and wireless clients, I experienced annoying interruptions while streaming music. They appeared kind of random but consistently at any time of day…for months on all clients. Playback would pause, just to continue after some seconds, as if the buffer was empty. Also, the playback rarely had some timing issues. It sounded like all of a sudden 50ms of music were skipped, causing a small rhythmic annoyance.
So I have played around with the settings and it appears that, when I disable IP random ID the issue disappears. I am not 100% convinced though, since the issue appears randomly. Fingers crossed!? I can stream 4k videos fine (via amazon). I guess Apple Music is using a lot less buffering!?
RFC 1122: The IPv4 ID field MUST NOT be used for purposes other than fragmentation and reassembly.
So the question is probably something like: can the ip random id setting cause issues for packet fragmentation and reassembly? Under what circumstances? Is streaming affected? Should the setting be off by default?

Where is this setting located?

Don't disable that security setting, it cannot fix a poor internet connection or a lousy ISP

@CJ firewall - settings - normalisation
@newsense I will keep it off until I get another glitch! :)

It still happens… >:(
I am switching my ISP…and while I am at it from VDSL to fiber.
That also means I can say bye to pppoe.
I will have 5x the upload and double the download for only 20 euro extra. Good deal.

So I tried to solve this again today, turning all the levers. Still on my dsl line.
After switching off all the hardware support under interfaces -> settings the issue is gone.
That is on OPNsense 23.7.6-amd64 running on an apu2d4.
