Replication ports

[Dude]

Wasup Dudes.
I would like to know what ports uses DNS for replication
between primary and sec DNS server.
And 2nd if the zone iz ADinteg then it'll use AD
replication. What ports uses AD for replication?

179442 - How to Configure a Firewall for Domains and Trusts

Yeah man, there's about 30 ports for AD. I would suggest to use a VPN thru
the firewall instead of opening all those ports and turning it into Swiss
cheese.

As for strict DNS traffic between two W2k DNS servers, (not AD replication),
TCP 53 and UDP 53, and need to open UDP 1024-65534 for the response port. If
it were BIND, it would only need TCP 53 and UDP 53.

The shape of the hole that you knock into your firewall depends
from which sides of it the "master" and the "slave" are on.

Active Directory database replication is a different mechanism
entirely, of course. Unlike the "zone transfer" replication
mechanism, it is not an extension to the DNS protocol.
