Hello Everyone,
Could any one of you please tell me when the DNS Zone transfers (tcp/53)take
place. I am administrating an ALG firewall and have defined rules for DNS
Requests (UDP/53), but no rules are defined for DNS Zone (tcp/53), yet the
firewall is working fine. All the names are being resolved accordingly.
Under what circumstances, do I have to define DNS Zone rules. Who makes
these DNS Zone requests, I know it has to be DNS to DNS, but can a machine
other than DNS server make these requests.
Thanks in advance for your time and efforts.
Regards
Eessa
