I have multiple internal subnets which are all internally routed so that each subnet can reach all the others.
There is a Fortigate 6.4.9 to be accessing public addresses as usual and is connected to one of the internal subnets: subnet 1. It is the default gateway for all of the hosts on the multiple subnets.
host at subnet 2 has destination on some public address.
The internal routing sends the packet sourced on subnet 2 to the Fortigate internal address on subnet 1.
How are the other subnets best included in the Fortigate settings?
For example: I might want to set up an Address Group called INNER.
And, an Address range or Group for each of the subnets that would be included in INNER.
Does that make sense?
Where is the interface on the Fortigate to be entered in this case?
