Peplink Balance Series

C.2 Maintaining the Same IP Address throughout a Session

C.2.1 Scenario

Some client IP address sensitive web sites (for example, Internet banking) use both client IP address and

cookies matching for session identification. Since different IP addresses are used during the load

balancing, the session is dropped when a mismatching IP is detected.

C.2.2 Solution

Make use of the Persistency functionality of Peplink Balance.

With Persistence is configured and the option By Destination is selected, Peplink Balance uses a

consistent WAN connection for source-destination pairs of IP addresses, and prevents sessions from

being dropped.

With Persistence is configured and the option By Source is selected, Peplink Balance uses a consistent

WAN connection for same source IP addresses. This option offers even higher application compatibility

but the outbound traffic load will be distributed more evenly only if more users use the Internet.

C.2.3 Settings

Set persistence in:

Network > Outbound Policy > Managed by Custom Rules

Click Add Rule, select HTTP (TCP port 80) for web service, and select Persistence.

Tip

A network administrator can use the Traceroute utility to manually analyze the connection path of a

particular WAN connection.
