For a list of interactive and secure ports that are automatically forwarded, see
Appendix A, “HP EFS WAN Accelerator Ports.”
The following table describes the in-path rules.
The HP EFS WAN Accelerator applies rules in numerical order starting with rule 1. If
the conditions set in the rule match, then the rule is applied, and the system moves on
to the next packet. If the conditions set in the rule do not match, the system consults
the next rule. For example, if the conditions of rule 1 do not match, rule 2 is consulted.
If rule 2 matches the conditions, it is applied, and no further rules are consulted.
Rule Type Description
Auto-Discover Auto-discover rules automatically find the HP EFS WAN
Accelerators between this HP EFS WAN Accelerator and the
server for which the packet is destined. When HP EFS WAN
Accelerators are found, the HP EFS WAN Accelerators
work together to optimize the connection. By default, the HP
EFS WAN Accelerator automatically intercepts and
optimizes traffic on all IP addresses (0.0.0.0) and ports (all).
Defining in-path rules modifies the default setting.
Fixed-Target Fixed-target rules directly specify out-of-path HP EFS WAN
Accelerators near the target server. Determine which servers
you would like a particular HP EFS WAN Accelerator to
optimize (and, optionally, which ports), and add rules to
specify the network of servers, ports, port labels, and out-of-
path HP EFS WAN Accelerator to use.
If you have an out-of-path configuration with failover
support, you specify the master and backup HP EFS WAN
Accelerator in the Setup: Optimization Service - In-Path
Rules page.
In an out-of-path deployment, if you want to optimize MAPI
Exchange by destination port you must define a 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, see “Optimizing MAPI Exchange
in Out of Path Deployments” on page 40 .
Pass-Through Pass-through rules identify traffic that is passed through the
network unoptimized.
Discard Packets for connections that match the rule are dropped
silently. The HP EFS WAN Accelerator filters out traffic that
matches the discard rules.
Deny When packets for connections match the deny rule, the HP
EFS WAN Accelerator actively tries to reset the connection.
