First time buying Fortinet
First time posting there, so I've not much experience with fortinet i mean its first time I'm planning to use fortinet because of my work.I want to know which model will be better to use in this situation.
So as you can see on attached picture it's the diagram of network. right now there is only a mikrotik router.
Main thing for this diagram is i use linux server for DB and on windows server there is class 5 softswitch for VOIP. right now on mikrotik there are just several ports opened UDP ports 50000-60000 and also a few SIP ports 5060,5061 and a few more also I've 1 IPsec VPN on it.
As i've said i want to add fortinet and looking for a hardware model which can i use. also about router should i keep that mikrotik or can i just put it in trash and leave only fortinet ? also do i need any license for that firewall?
I've 2 uplinks both 100/100MB bandwidth.
