The jails are on the host with LAN behind it and with ipf firewall which 
allows out anything coming from LAN private ip address. I was not able 
to get this to work until I discovered the jail needed a copy of the 
hosts /etc/resolv.conf. Now it works without any special tweaks, and the 
dymanic ip address changing causes no problems.
