Need Help setting up security lab on GNS3

Hey Folks,

I'm working on setting up a security lab on GNS3 for a presentation on Cybersecurity concepts. It's been almost 10 years since I've lost touch and lot of things have changed so I am in need of some help / advice on best way to set things up. Here is a sample lab I'd like to setup which should comprise of the following security devices and had following questions:

1. Cisco Firepower (FTD) --> What is the ideal way to mount it ? On a virtual box or on a remote VM ? If it is mounted on the GNS3 VM, I guess it won't work because the firewall would need its own network adapters. Also remote VM might not work as I was able to mount this on a remote GNS3 VM server on google cloud and connect to gns3 but was unable to connect to other devices as the ip address is public?
2. Web application firewall --> Is there any image / appliance that is supported by GNS3 ? Should it be mounted on GNS3 VM or installed on virtual box?
3. IDS / IPS --> Is there any image / appliance that is supported by GNS3 ? Should it be mounted on GNS3 VM or installed on virtual box?
4. Cisco router with netflow enabled
5. Email security gateway (if possible) --> Is there any image / appliance that is supported by GNS3 ? Should it be mounted on GNS3 VM or installed on virtual box?
6. SIEM --> --> Is there any image / appliance that is supported by GNS3 ? Should it be mounted on GNS3 VM or installed on virtual box?
7. VPCS
8. Windows server --> Should it be mounted on GNS3 VM or installed on virtual box?

Many thanks in advance.
