Hi,

I'm planning to install 3 ESA C300V and i would know what interface will be used when enabling cluster with CCS ? Management, Data1, Data2 ?

Many thanks

regards

If I remember correctly, outbound it will use the one that's closest to the other box from a routing perspective.

In the same data center, I put the management interfaces on the same subnet and tell the boxes to connect to one another via the management ip.

In separate data centers I would put a route in for the management networks via the management interfaces default gateway.

I prefer to use MGMT Interface each flat network of Manmangment (no Firewall involved between devices)

Look at the guide Lines and config :
