Question

Active Active HA

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 @sjoshi 

Already read the article, but still confuse related ip address configuration for active active scenario. Should each LAN interface from fortinet use same ip address or different ip address?

Both the FGT will have the same IP address for all interface
