2 DSLs on Balance 20, some sites misbehave

I have 2 DSL lines as WAN1 and WAN2 (needed for speed in very slow service area).

Some sites seem to get very “confused” about the connection, with, for example, hosting control panel “cpanel” constantly logging me out saying my IP has changed, or another site doing something similar, but without error message.

If I disable one of the WANs the problem goes away.

What is the best way to deal with these issues?


An outbound policy rule is needed for the “cpanel” application. You can add a rule for this under Network> Outbound Policy and the source, destination, or traffic type can be specified. The “persistence” algorithm would still allow you to load balance these outbound sessions.
