Overlay network: VPN and internal communication with LAN
I own a Firewall Blue Plus. Now I am searching for a way to secure my IoT devices. One thing I want to do route traffic from IoT devices over VPN. I learned that all devices that want to use VPN must be placed in overlay network of Firewalla Plus. That is a lot of work to do, but okay.
My question is: Will I be still able to communicate with devices in overlay network out of the main network? So will I still be able to send commands to my IoT devices from my smartphone for example?
And a second question is: Will requests of these devices still be blocked if a rule matches when choosing not to "Force DNS over VPN"?
First, do some research on VPN + IoT security. Meaning, in theory, VPN is a transport that hides your traffic from ISP's ... meaning, do you see your ISP as more dangerous than VPN providers?
Q1: Overlay network is just a network, you should be able to see it from your main network. But for the blue+, the DHCP will run on the overlay with the blue+ as the gateway, so unless you static IP your device, they will always end up in the overlay network with the blue+ as the default gateway.
Q2: Let me get someone to reply to you within 24 hours.
