currently i have DC with Windows Server 2008 R2 and Exchange Server 2007 with CAS,MB and HT installled on the same machine. i have only one firewall which is Cyberoam.
my future plan after upgrade to exchange 2010 is:
-> Total three servers with CAS,HT and MB servers installed on each
->DAG will be used on MB Servers and Hardware Load Balancer (Kemp 2000) will be used for CAS
->TMG will be introduced after Cyberoam (public IP will be on Cyberoam)
->There are two public IP on Cyberoam, one for the internet for the users which will forward traffic on TMG, other will be for Exchange which will forward traffic to Edge Transport Server.
->Two seperate Edge Transport Servers in WNLB in the DMZ (between Cyberoem and TMG)
Q1) i have studied different stuff on the internet but i need to know that what will be steps i.e which one to do first, which one to do second e.t.c.?
Q2) is it enough to route all my public clients (pop3, anywhere,OWA) from Cyberoam to Edge Transport Server or still i have to configure publish rules on TMG?
