Re: NAT problems 14.3+

had to quickly upgrade to 14.4 again to return to the broken state. But =
unfortunately -tso -lro does not change the result.

ice0: =
flags=3D1008943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,LOWER_UP> =
metric 0 mtu 9000
	=
options=3D4e00028<VLAN_MTU,JUMBO_MTU,RXCSUM_IPV6,TXCSUM_IPV6,HWSTATS,MEXTP=
G>

using
ifconfig_ice0=3D"DHCP mtu 9000 -tso -lro -vlanhwtso -vlanhwtag =
-vlanhwfilter"

Inside the jail, the ISP dns stops responding then too strangely. Then =
when i update it to 1.1.1.1 i can resolve again inside the jail.
Then when i ping some domain, the first reply i get is from the resolved =
ip and then i get responses from its own server ip.

(jail)
root@x-mysql:~ # ping nu.nl
PING nu.nl (2.16.245.135): 56 data bytes

Maybe this can be a clue? (i dont remember seeing this before today)
