So I need some help. I'm in the process of putting together a raspberry pi vpn router using 2 usb wifi dongles. What I'd like to be able to do is once the initial setup of the captive portal has been done on the first wifi connection I want to then be able to login to a web portal on the pi that will allow the user to then select the wifi network that they want to connect the 2nd wifi nic to that will then have the VPN run over it. Ideally I'd like to know of any guides for controlling a nic via a web portal. To further move it on I'd want to try and do a similar thing for the VPN connection. If anyone has any ideas or links I'd be most grateful, thanks.
