Re: [FW-1] Zone transfer via DMZ



TCP/53 for zone transfers and long name queries.  UDP/53 for short name
queries (most traffic).

Subject: [FW-1] Zone transfer via DMZ

I have the following problem. (FW-1 4.0)

We just set up a DMZ in which a direct connection to another company is
made. I can connect to some IP-numbers in their subnet, but I need to be
able to do a zone transfer from their DNS server. From the FW I can do a
nslookup to their server, but from my LAN I cannot. What am I missing
here?

Their DNS server is only for Internal use.
