Actually, sorry I misread your capture - it is using the same address so
doubt it the problem of interfaces......
Are you are not getting any logging in debug when the ACK comes in?

Hey Mino,
From your packet captures above it looks like your ACK is coming in
another IP address. I also see that you are doing the packet capture across
all your physical interfaces (-i any). Perhaps your Kamailio is only
configured to listen on the one interface (the one *not* getting the ACK).
To test limit your packet capture to only the interface/s that you know
Kamailio is listening on.
Cheers
Jason

We are troubleshooting this issue almost for 2
days and we did not find
the solution yet. The thing is, that it does not enter even the config file
(we have some debug messages at the start, that do not show). Otherwise we
do not have any problem with ACK, but only this particular ACK is not
forwarded... Was there some bug related to parsing in 3.1.0 which would not
print any error to syslog?

Seems like a loose routing issue. Are you loose

You can use something like wireshark on Kamailio
server to see if ACK
packets go in right direction.
I had problem with ACK and BYE, and I saw that in some cases ACK and
BYE packets looped back in kamailio.
May be I used wrong client.
