Best way to Eval Fortigate

[Simon_Bingham]

I'm a network guy, familiar with Juniper SRX and Palo a bit. 
I've installed FortiGate in Eve-NG  but the licences have now expired. 
What's the best root here for licencing? Ideally, I would like something permanent 
Performance is obviously not important. But it is really great to be able to simulate scenarios similar to the live ones we are deploying. 

I have asked our SE for temporary licences, but now, at the 3rd request, I've been politely asked to find a different solution. 

What is my best bet here for a permanent solution ? or is there a easy route to just keep renewing temp licences. 

Most vender seem to make trial licences freely available. 

Thanks in advance,

Check if the permanent trial license features meets your requirement . The FortiOS permanent trial license requires a FortiCare account. This trial license has limited features and capacity. See VM permanent trial license for details.

Thanks, this is no use, "3 firewall policies" and "3 interfaces" @fortinet. The best thing you could do for us is a VM that supports everything !!! Then we can test out customer scenarios and cripple the performance to something very slow like 1mbps or 100K !!  , I'm using an SRX in place of a FortiGate in my labs to simulate NAT and BGP as done by a Fortigate in the production environment. I would much rather use a FortiGate VM.
