New here, I see you have proxmox running on two of the servers. What’s the third one running? Haven’t seen the icon before.

Awesome graphic btw

Not enough arrows.

You need a core switch though. a better core switch.

Also, for dickhead, that final network, I would use 10.255.255.0/24 with .254 being the address of the router/firewall. That is my recommendation. if you ever see a router or subnet with that address I have been there. It helps me orient myself when designing a network with multiple subnets and plans.

Nice setup. Frankly, I am a little turned on by it. I just got done installing my Dream Machine SE.
