Hi,

I need the following problem to be solved:

I got my internal net 192.168.10.0/24 and a DMZ 192.168.0./24 connected 
by m0n0wall. In both subnets are DNS (MS DNS internal, BIND DMZ) 
servers. The DNS server in my internal net has the master zone for my 
domain and the DNS in the DMZ has a slave zone. The problem is that 
replication does not work properly. I checked syslog on my Linux box 
running BIND and found:

Sep  2 12:13:30 <LINUXBOX> /usr/sbin/named[11906]: refresh_callback: 
zone foo.bar/IN: failure for 192.168.10.100#53: timed out
Sep  2 12:13:30 <LINUXBOX> /usr/sbin/named[11906]: refresh_callback: 
zone foo.bar/IN: 192.168.10.100#53: retries exceeded

I need to know how to setup rules for this to work!

Thanx

Sven
