Fortigate Deployment two geographically separate data centers.

[kris1]

Hey guys,

we are going to deploy 2 fortigates in transparent mode in the internet segment in two different data centers, 

what are the requirements to configure HA between them ? does both fortigate needs to have L2 connections between

them ?

Have you read this document allready?

Do you really need HA between 2x GEO locations?

Does the layer3 device have redundancy built in?

would you be better deploying 2x  transparent units per-DC and using the  STPprotocol to establish link-redundancy ?

And yes for transparent you will need layer2 connections ( 2x interfaces )
