--- Comment #3 from Nicolas Fella <nicolas.fe...@gmx.de> ---
I think I somewhat understand what is going on.

The UDP packet is too large to fit within the maximum transfer unit (MTU),
usually 1500 bytes, or 1472 usable bytes. Therefore the "bad length 1631 >
1472" warning.

While it seems possible to get around that via packet fragmentation this is
apparently handled differently by devices. This could explain quite some
"devices can't see each other" reports.

I'm not quite sure how to address this. An obvious approach is to reduce the
size of the identity packets, but that would be an incompatible change and
would require careful rollout
