Exchange 2013 NLB Client Connections

Question

Hi everyone, I'm
setting up an Exchange 2013 system,
the infrastructure that will be mounted
as follows:
-> 2 Domain Controllers
-> 2 Exchange 2013 backend servers
for DAG mailbox
-> 2 Servers frontend for
client connections on Microsoft NLB.
My question is regarding the Fronted
Microsoft NLB servers, I understand that
you have to redirect all SMTP and
IMAP traffic, POP, HTTPS, AS
... to distribute all Fronted
connections to servers (NLB shared
IP to the cluster).
This is correct?
thank you very much

If you want to "Load balance" them, yes. Note that WNLB doesn't do such a great job at this and is typically not recommended as its not application aware.
Not sure what  you mean by "NLB shared
IP to the cluster)" The client connections go to the CAS roles, not the DAG cluster IP
