Quoting ed <[EMAIL PROTECTED]>:
Zone transfers are on tcp/53, DNS lookups are 53/udp, so: pass in on $ext_if proto udp from any to $DNS port 53 keep state and if required: pass in on $ext_if proto tcp from $ext_net to $DNS port 53 keep state I use TinyDNS here, so we don't really need to transfer zones as its handled with a single data file. CARP can be good with DNS.
Ok. This 2 servers DNS masters. But if the one server will master(CARP master,not dns) and other CARP slave, zones sends only from CARP master and I need some sync tool such as rsync to syncing zones files between 2 master DNS servers(one master CARP and one slave CARP)? Or if I want to do load balancing with CARP, how it affect on BIND?
