Thanks, Jon, I thought it would work with either but I added a udp line
before the tcp line.
pass in on $ext_if inet proto udp from any to ($ext_if) port 53 keep state
pass in on $ext_if inet proto tcp from any to ($ext_if) port
$tcp_services flags S/SA keep state
and it works. Hmmmm......, I wonder if there is something else that I
need to add to udp?
Thanks,
ed
