Hi,

I have a jail setup on 4.8-p13 with host natd-ing as usual
for the jailed virtual m/cs. For no apparent reason, NATD
from internal jailed environment to outside stopped 
suddenly. The port forwarding from host to jail env-s were
still working fine. Although a reboot fixed the problem, 
I am still trying to figure out if this was a problem with
my setup or not. The machine was running fine for a while,
although I wouldn't know for sure when it started failing
(I haven't done any outgoing ftp/ssh/fetch anything from the
jailed env-s for a while)

Here is my natd config.

rdr rl0 192.168.2.3/32 port 40961 -> 172.16.1.1 port 40961
rdr rl0 192.168.2.3/32 port 40962 -> 172.16.1.2 port 40962
rdr rl0 192.168.2.3/32 port 63788 -> 172.16.1.2 port 63788
rdr rl0 192.168.2.3/32 port 40963 -> 172.16.1.3 port 40963
rdr rl0 192.168.2.3/32 port 40964 -> 172.16.1.3 port 40964
rdr rl0 192.168.2.3/32 port 5901 -> 172.16.1.3 port 5901
map rl0 172.16.1.0/24 -> 0/32

ipf firewall is enabled - however, it is an empty set.

pass in quick on lo0 all
pass in quick on rl0 all
pass out quick on lo0 all
pass out quick on rl0 all

Where do I start looking to identify this issue?

The only thing that I could find in my /var/log related to network
was occasional messages from dhclient

Nov 21 09:31:48 mach00 dhclient: New Network Number: 192.168.2.0
Nov 21 09:31:48 mach00 dhclient: New Broadcast Address: 192.168.2.255
Nov 22 13:31:15 mach00 dhclient: New Network Number: 192.168.2.0
Nov 22 13:31:15 mach00 dhclient: New Broadcast Address: 192.168.2.255
Nov 23 17:33:44 mach00 dhclient: New Network Number: 192.168.2.0
Nov 23 17:33:44 mach00 dhclient: New Broadcast Address: 192.168.2.255

Although I am running DHCP for a main host's IP, it never changes
(and has never changed)

Any help is appreciated.
