Hello, I’m just learning so all hints about the current configuration welcome 
I’m learning how to do Vlans and overall I think I’ve configured everything the way I’d like, I have vlan 30 and I’d like it to be something like a DMZ zone. I have separated a file server and a private web server into this vlan. Unfortunately both servers do not have internet access. How would you guys be able to advise what to improve / fix in my configuration I would be very grateful. Device is hAP ax3
