I have similar problem with bridging tap0 and lagg0 (lacp). Problem I think is beetween lagg0 and tap0. I can see ICMP traffic from guest to host on bridge0 interface (ping), but no tcp (ssh). Tcpdump on host on tap0: host: 192.168.22.19 guest: 192.168.22.135 tcpdump: listening on tap0, link-type EN10MB (Ethernet), capture size 65535 bytes 09:05:17.641006 IP (tos 0x0, ttl 64, id 8317, offset 0, flags [DF], proto TCP (6), length 60) 192.168.22.135.41140 > 192.168.22.19.ssh: Flags [S], cksum 0x3133 (correct), seq 2326804792, win 29200, options [mss 1460,sackOK,TS val 2027493701 ecr 0,nop,wscale 7], length 0 09:05:17.641100 IP (tos 0x0, ttl 64, id 21800, offset 0, flags [DF], proto TCP (6), length 60) 192.168.22.19.ssh > 192.168.22.135.41140: Flags [S.], cksum 0xae19 (incorrect -> 0x4e8f), seq 3120117570, ack 2326804793, win 65535, options [mss 1460,nop,wscale 6,sackOK,TS val 941632328 ecr 2027493701], length 0 and silence on bagg0 and lagg0. I can't connect to jails on host too. Traffic for other hosts on the network works fine.

Benjamin Perrault has observed a massive slowdown in host to VM networking with a combination of bhyve VirtIO/lagg and bridge. Works fine to the outside world but not between the host and VM. Must investigate.
