HA between different network

Hello everyone,

I wonder if it possible to put HA on 2 fortigate which have 2 different addressing plan.

In fact, I'm trying to set up the HA on two different sites with active-active standalone (FGSP). But the config between 2 fortigates is not synchronized. Moreover, if I am using the same addressing plan for HA link, HA works and config is synchronized.

Can you help me ?

Best regards,

Quentin
