Sorry, that's my fault - i overlooked your request for a test with pf enabled. The example-ruleset is attached again. I added a line to allow the incoming ping to 5555. I don't see a difference until i enable the redirection to the jail which makes the packet with extended data-length fail. Once i disable RXCSUM it works.
