High Availability between 2 Fortigates 301E connected to 2 ISP links ?

[Lipe79]

Hi everyone! 

I need your precious help about this scenario, please see attached diagram below.

What do you recommend as being the best way to configure HA on these 2 Fortigates to work properly?

Active-Active or active-passive

Each one of the Firewalls is connected to ISP through only 1 link and the ISP is the same but has configured VRRP between ISPRouter1 and ISPRouter2.

Thank you so much!  Regards!

Hi James_G and Lobstercreed,

I did not test the link monitor 'solution' yet because I'm in another country and this equipment is installed far from here so I'm going to test next month but I have some doubts if it will result.

Could you please explain the steps I have to do to configure the 3 different vdoms as you said and if I need to change all of my configuration completely?

Thanks for your support!

Regards
