Fortiweb Deploy Design

Hello Community,

 

I hope you're well

 

I stay in process to  deploy  Fortiweb 400 F, but I have doubts about whether it is advisable to place the Frontend and Backend interfaces in separate VLANs, and if you recommend this topology for a future deployment of Adoms, or if the design should be rethought.

I attach the Topology.

Greetings!!!!

Hello Rodrigo,

I hope you are doing well too :)!

 

You can find here an interesting document:

https://docs.fortinet.com/document/fortiweb/6.4.3/administration-guide/211763/planning-the-network-topology

 

I hope it is helpful.

 

Anthony

    Hi Rodrigo

    As described on the doc shared by Anthony you can because FWB is a firewall and as a perimeter device it is correct to connect it to both FE and BE networks.

    And also like any router/firewall, it is also possible to set it up as a one arm firewall.

    So both are correct. But sometimes the first or second option is preferred depending on the global context.
