Transparent Mode with multiple interfaces

[avilt]

Can I implement FortiGate-200B firewall in transparent mode with more than two interfaces?

A transparent mode FGT operates in Layer 2 mode (OSI model), i.e. as a bridge. You can (probably) use all physical ports. All these ports will have the same IP address so it' s like connecting to a switch. The comparison to a switch is not 100% correct, as the FGT can do more things than just forward traffic (like terminating a VPN).

Yes, bundle multiple ports into zones. 1) put the 200B into interface mode (versus switch) 2) consider putting the ports destined for transparent mode into their own vdom 3) create zones for either or both sides (one <-> many or many <-> many) 4) create firewall rules for each direction of the flow
