40 2 - C ONFIGURING THE HP EFS WAN A CCELERATOR
‹ MAPI Exchange 2003. Configure the MAPI Exchange 2003 port if you have an
internal firewall specifying a port for Exchange data. This option is not
commonly utilized.
‹ MAPI Exchange 2003 Acceleration. Enables MAPI 2003 Acceleration which
allows increased optimization of traffic between Exchange 2003 and Outlook
2003.
‹ MAPI Transparent Prepopulation. MAPI transparent prepopulation allows
email data to be delivered between the Exchange server and the client-side HP
EFS WAN Accelerator while the Outlook client is off-line. When a user logs in to
their MAPI client, the mail is already waiting in the client-side HP EFS WAN
Accelerator and can be retrieved locally. This feature enables email to be
optimized even though it has not been seen before by the client.
‹ Name Service Provider Interface (NSPI). NSPI is the address book
subcomponent of the Exchange protocol that is optimized by the HP EFS WAN
Accelerator. In certain situations (for example, clients connecting through a
firewall), you might want to force a server to listen on a single pre-defined port so
that access to ports can be controlled or locked down on the firewall.
Optimizing MAPI
Exchange in Out of
Path Deployments In out-of-path deployments, if you want to optimize MAPI Exchange by destination
port, you must define fixed-target, in-path rules that specify the following ports on the
client-side HP EFS WAN Accelerator:
‹ Port 135. The Microsoft end-point mapper port
‹ Port 7830. The HP EFS WAN Accelerator port used for Exchange traffic
‹ Port 7840. The HP EFS WAN Accelerator port used for Exchange Directory
NSPI traffic
For detailed information about defining in-path rules, see “To set a fixed-target rule”
on page 31 .
If you changed the Microsoft Exchange Information Store Interface (MEISI) port in
your environment, in the Setup: Advanced Networking - Protocol MAPI page on the
client-side HP EFS WAN Accelerator, change port 7830 to the static port number you
have configured in your Exchange environment.
For further information about changing (MEISI) ports, see the Microsoft Exchange
Information Store Interface at http://support.microsoft.com/default.aspx?scid=kb;en-
