cahe-only DNS in jail

[Matt]

I'm experiencing strange behaviour with Bind running inside a jail.  I'm 
running 5.2.1 current in the jail.  Thinks are working, but poorly.  
Lookups for my local machines work perfectly.  Some remote lookups work 
fine (yahoo, google, etc...).  However, many lookups time out, but will 
succeed after a few tries.  I'm doing all this from home (comcast cable 
internet).  Anyway, I'm not sure what to do.  Sniffing the network 
doesn't seem to help much.  Queries and requests are reaching the right 
hosts and ports.  Thanks for any help.
