And I can confirm you that the problem does not happen in the same topology with a FreeBSD 10.3 host. At this point I guess that all responses to ICMP requests received on IP addresses assigned to jails linked to specific FIB on FreeBSD 11.x are not influenced by the FIB, while in FreeBSD 10.x they are. (No problem from ICMP traffic generated from the jail itself: I saw packets leaving and coming back through the right interface). Unfortunately I haven't the competence to point you to the right direction to solve, but I think it is a jail-related issue, thus this should be the right mailing list to discuss about this. I'll come back if I'll be able to understand something more.
