I just wondering if I want to use LAN to LAN VPN link used for PEAP Authentication.
The configuration like below:
Client —> AP (Radius client) —> LAN to LAN VPN —> Radius Server (PEAP)
I assumed that LAN to LAN VPS already use encryption channel then the PEAP authentication for client also use encryption.
Is it possible with this configuration?
Do not worry, it works. Do not forget, that an OpenVPN VPN with TAP virtual devices acts as a virtual Ethernet connection. Hence, any layer 2 traffic (and not only IP protocols) can cross the VPN.
