Set up two Exchange 2010 servers / Windows Server 2008 R2 SP1
1. Edge tansport server role in DMZ (10.0.0.X) (Two NICs - one is for 10.0.0.X, the other one for 192.168.2.x)
2. Hub transport /CAS/Mailbox server inside LAN/Domain (192.168.2.X)
I have no problem to resolve DNS name of Hub/CAS/Mailbox server role from Edge transport server role but
can not resolve DNS name of Edge transport server role from Hub/CAS/Mailbox server role.
In short (DMZ -> LAN) DNS name resolution - no problem
(LAN -> DMZ) requested timed out. (All ports are open in LAN -> DMZ)
Host file has been created, A record is added, DNS server set up is all according to Microsoft TechNet paper instruction.
I can't perform Edge Subscription unless I know they (Edge/Hub) can resolve DNS name for each other.
Any ideas? Please help.
