Just to spread the word - I've added comment about my situation with some more test with tcpdump: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240106#c3 To make it short here: if I add static ARP entries for IPs on host's and jail's vlan interfaces, then ICMP requests reach host's vlan interface, but replies doesn't return to jail. All tcpdump output is in my comment in PR, see link. -- Best regards, Alexander Lunev
