udp port 4932

[Aziz Bouassab]

Dear all,
I noticed that our dns server send many query's to other name servers using 
source port 4932 and destination port 53, but the problem is that those name 
servers reply to my dns server with source port 53 and destination udp 
4932,as sequence udp port is denied on my firewall.

Does anybody know about this?

Thanks
