Maintaining the Same IP Address throughout a Session

C.2.1 Scenario
Some IP address sensitive web sites (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 mismatching IP is detected resulting in frequent interruptions while visiting such sites.
C.2.2 Solution
Make use of the Persistency functionality of Peplink Balance. With Persistence configuredand the
ByDestinationoption selected, the Peplink Balance will usea consistent WAN connection for source-
destination pairs of IP addresses,preventing sessions from being dropped.
With Persistence is configured and the option By Sourceis selected, 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:
Network> Outbound Policy
Click Add Rule, select HTTP(TCP port 80) for web service, and select Persistence. Click Save and then
Click Apply Changes on the top right corner to complete the process.
Tip
A network administrator can use the Traceroute utility to manually analyze the connection path of a particular WAN
connection.
