Hi Serguei,

If you are interested to investigate it further, please let me know as I said I have a cluster with these 2 rules configured.

In another case I noticed that user-defined chains are a way to
circumvent these types of functional restrictions. If that's good or bad
is up to you to decide. ;)

Regarding the desired functionality, I guess you're wandering the
sinkhole-filled plains of undefined behaviour.

Cheers, Phil
