I experiment the same problem with rb333 and 532Ar5…
I’ve a sequence of packet loss every 30-40 ping. more in high traffic load.

I use rb 333 only with 2 ethernet port. I use /ip firewall mangle and /ip firewall nat and I lose packet in sequence…

ros v. is 3.2

with 3.7 paket loss is now ok …

thx for release 3.7…

My rb continue losing packet also with 3.7…
It loss packet only on ethernet interface..
I’m going crazy!
