Hello everyone,
First of all thank you for reading my post, as the title states i'm in a position where I need assistance as my problem is out of my reach.
I have a business network composed of :
3 switches (one of which is PoE)
Fiber optic router
QNAP server for data backup
A server that act as our Primary Domain Controller
CISCO PBX for our VoIP
And other equipments such as DVRs for IP cameras ...
I recently bought a Fortigate 60E series next-gen firewall since we don't have one and it's a necessity when it comes to network security, the configuration has been easy enough.
When I connect my computer directly to the firewall's LAN port while the WAN is connected to a fully working Router, everything seems to work, I have access to the internet and all the web/app filtering + policies seem to work just fine. But when I try to install the firewall on our switch so that everyone goes through it before they access the internet it does not seem to work.
Internal interface : 192.168.1.99
Wan interface : 172.16.0.2 (subnets have to be different)
When connected directly to the firewall I can ping both interfaces without a problem, but it's not the case when I install it on the network.
If you have an idea on the nature of the problem I would very much appreciate your feedback, I feel like i've reached a dead end.
PS : I'm not an expert on networking.
Thank you, and good luck for all of you.
