Minimum Gateway Instance Size for FireNet deployment
The minimum gateway instance size for FireNet deployment (for TGW FireNet or Transit FireNet) is C5.xlarge. This is because the FireNet gateway requires four network interfaces:
-
eth0 as a management interface
-
eth1 as a TGW interface (TGW FireNet only)
-
eth2 as a firewall instance interface
-
eth3 as the HA FireNet gateway interface
The private interfaces on FireNet Gateway are described as below.
