I have ASL box with 3 net cards (EXT, DMZ, INT).
Must setup primary domain server for my domain.
I am planning to put bind server to the machine inside DMZ.
Which is best for outside (internet) users to access domain server:
1: ASL DNS proxy is enabled, with forwarding name server set to real primary domain server (in DMZ),
On ASL: Interfaces to listen on: all three (EXT, DMZ and INT), Allowed Networks: ANY
2: ASL DNS proxy is disabled, and all DNS traffic is NAT-ed to real DNS server through ASL.
My first choice would be with DNS proxy enabled,
but in this case I am a little bit concerned about zone transfer to my secondary DNS server on my ISP.
So, which way is better?
Thx all!!!
