problems w/forwarders

[Kevin Darcy]

BIND 4 always used port 53 as a query source; BIND 8 uses a random unprivileged
port by default. If you have source port filtering in effect on an intervening
firewall or router, you may need to relax the filter rule, or use the
"query-source" option of BIND to lock it back in on port 53.
