Maintaining the Same IP Address Throughout a Session

C.2.1 Scenario
Some IP address-sensitive websites (for example, Internet banking) use both client IP
address and cookie matching for session identification. Since load balancing uses
different IP addresses, the session is dropped when a mismatched IP is detected,
resulting in frequent interruptions while visiting such sites.
C.2.2 Solution
Make use of the persistence functionality of the Peplink Balance. With persistence
configured and the By Destination option selected, the Peplink Balance will use a
consistent WAN connection for source-destination pairs of IP addresses, preventing
sessions from being dropped.
With persistence configured and the option By Source is selected, the Peplink Balance
uses a consistent WAN connection for same-source IP addresses. This option offers
higher application compatibility but may inhibit the load balancing function unless there
are many clients using the Internet.
C.2.3 Settings
Set persistence in at Advanced>Outbound Policy.
Click Add Rule, select HTTP (TCP port 80) for web service, and select Persistence.
Click Save and then Apply Changes, located at the top right corner, to complete the
process.
A network administrator can use the traceroute utility to manually analyze the connection path of a particular WAN
connection.
