Mobile VPN'd hotspot?
-
I have a concept of something I would like to set-up if I can figure out how to do it.
I have pfSense running at home. When I connect to a public WiFi hotspot from my laptop, I always VPN home, using OpenVPN, which gives me access to all my networking resources in my house. I am in the process of buying an RV and thought of building a small device that will be able to tap into a WiFi hotspot, then using a VPN, route all traffic through my home pfSense, then create it's own low-power hotspot for just my RV that I can log into. I realize that some stand-alone devices are designed to log into one WiFi hotspot and then create it's own hotspot to share one connection, in fact, all three of my vehicles have this built-in, but I would like to route all the traffic through my home network, so I don't have to actually set up a VPN service on each of my devices. If this is possible, could it be further possible to have it login to a hotspot with a captive portal? I know one particular camping area where you "purchase" a code that you have to enter in via a captive portal. If I could do this through such a wireless gateway I have described, I wouldn't have to log both my wife & I's iPhones, iPads and laptop computers to access it, just the gateway, then we could all use the one connection.
Can anyone point me in the right direction for such a setup?

The difficulty with setting something like that up is that the wifi config in pfSense is not intended to connect to dynamically like that. There is no easy way to have it scan for wifi networks and present you with a choice to connect to. Or as you say to work past a captive portal. Though that could be done from a client the first time it connected as long as it wasn't being routed through a VPN that could not connect at that point!
It's probably not practical currently IMO.
