Hi,
We all know that when a DNS query is made, the reply may come back
using TCP if the response is too large.
The TCP reply won't be initiated by the remote site. If the response
is too large for the DNS server to send back in a single UDP packet it
will tell the client to request via TCP. All you need to make sure of
is that both tcp and udp port 53 are open from your caching dns server
to the outside world.
Thanks, Bill,
That makes more sense than what I had in mind.
Regards,
Ugo
