Hello
The in-kernel nat works on the external lupus interface:
lupus (jail) <-> bridge (hoster net)
eugene@lupus:~$ ifconfig inet0
inet0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0
mtu 1500
options=60000b<RXCSUM,TXCSUM,VLAN_MTU,RXCSUM_IPV6,TXCSUM_IPV6>
ether 02:35:28:c4:b0:0b
inet *.9.0.242 netmask 0xffffffe0 broadcast *.9.0.255
inet *.9.0.244 netmask 0xffffffff broadcast *.9.0.244
groups: epair
media: Ethernet 10Gbase-T (10Gbase-T <full-duplex>)
status: active
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
From the host side where lupus is running it looks like this (ixl0 - physical
iface, inet0 - bridge, epair110a - lupus):
ixl0: flags=1008943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,LOWER_UP>
metric 0 mtu 1500

I tryed 'ifconfig ixl0 -txcsum -rxcsum', but it did not fix the checksum
problem.
