Hi all,

From what I understand, zone transfer is requested by secondary, which means
pull from primary by secondary. I am wondering if the process can work other
way around, push from primary to secondary? The reason being is that I want
put secondary in DMZ (for remote users) and primary inside of firewall. If I
can configure primary push to secondary, then I don't have punch a whole on
the firewall. But if I do have to punch a whole, is the port number still 53
for zone transferring same as query? Thanks!
