Hello,

While still struggling with the rebooting problem, I notice that 
sometimes packets are getting blocked outbound from my LAN.  I have 
this set as the default - to allow anything out.  Here is an example 
from the log:

08:43:43.568570 rl0 @0:13 B 192.168.x.x,51747 -> 192.168.y.x,143 PR tcp 
len 20 62 -AFP IN

As you can see this is a LAN machine attempting to connect to a test 
IMAP server on a test DMZ.

Why would this packet get dropped?
Thanks
Paul Phillips
