Active Active HA

[HS08]

When we configure the fortigate as Active-Active this mean we will have :

• 2 cable from both fortinet to the internet
• 2 cable from both fortinet to the LAN
• 1 cable for heartbeat.

Now i want to focus 2 cable from fortinet to the LAN. Should the LAN ip address on the fortigate side have different ip or same ip? If use same ip address, what should we configure on the core switch port? Should 2 ports on the core switch configured as L3 LACP, or should we configure as L3 but using VLAN?

Hi @HS08

On HA Active-Active scenario there should be different IP on LAN connection.
