DNS Slave Auto-Configuration, Ports

Virtualmin Theme version: 6.6

Operating system: CentOS Linux 5.2
Hi,

I'm placing another DNS for replicate my records, I follow the steps in: http://www.virtualmin.com/documentation/id,dns_slave_auto-configuration_...

But the slave server[200.126.12.201] is protected by a firewall that I can't change because, I'm going to solicite to the server network administrator to unlock some ports for works fine.

please tell me the ports that I need to solicitate to open on the slave server?

I understant that the port 10000, 53, are very basic for DNS replication and configuration but could be necesary another ports.

thanks!
