Add New Rule
Type. Select one of the following rule types from the drop-down list:
• Auto-Discovery. Auto-discovery rules automatically find the appliances between this
appliance and the server for which the packet is destined. By default, the appliance
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 appliances near the target
server. Determine which servers you would like a particular appliance to optimize (and,
optionally, which ports), and add rules to specify the Target Appliance and a Backup
Appliance IP address and port.
NOTE: In an out-of-path deployment, 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: the Microsoft end-point mapper port:
135; the HP EFS WAN Accelerator port for Exchange traffic: 7830; the HP EFS WAN
Accelerator port for Exchange Directory NSPI traffic: 7840.
• 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
appliance filters out traffic that matches the discard rules.
• Deny. When packets for connections match the deny rule, the appliance actively tries
to reset the connection.
Insert Rule At. Select start, end, or a rule number from the drop-down list.
HP EFS WAN Accelerators evaluate 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.
In general, you should list rules in the following order:
1. Pass-through. List the exceptions to optimization, first.
2. Fixed-target. List any fixed-targets for optimization, next.
3. Auto-discovery. Apply the default rule: optimize all remaining traffic. (The default
auto-discovery rule is listed automatically.)
Source Subnet. Type the IP address for the source subnet in the Source Subnet text box.
Use the following format: 0.0.0.0/0.
Destination Subnet. Type the IP address for the destination subnet in the text box. Use
the following format: 0.0.0.0/0.
Port. Type the destination port number, port label, or all in the text box. For information
about defining port labels, see
“Setting Up Monitored Ports” on page 118
