I'm after some pointers on where to start with VPNs.@sbiddle pointed out on this thread that: Slightly OT I hope you didn't have port forwards to your cameras and were using a VPN. Having port forwards to devices such as alarms, cameras etc is extremely insecure and should be avoided unless these are locked down to whitelisted IP's. This has reminded me to actually start doing something about VPNs.I've just had a Paradox alarm with an IP module installed and want to use the app (I opened the recommended Port 10000 for the duration of playing with the Paradox App to confirm it worked but then closed the port again). I'm also playing with a few other server-y bits and pieces that are all currently limited to the internal network but can see a day where it would be nice to access them from the outside. I will also very likely add IP cameras at some point too.My router has OpenVPN Server built in, but I don't really understand the configuration options, so first looking for some pointers as to best practice. Googling the options is either way over my head or has at least two people arguing which is the right option. Can anyone point me at a decent guide?Second, what's the best way of setting up a VPN client? I'd probably use this primarily on my (Android) phone to access the network, but also a notebook, although this would probably usually connect via tethering to the phone. Ideally, I'd like a simple toggle option for VPN on and off (I don't mind paying for an app if it offers benefits). Alternatively, is there a way to whitelist/filter by something like MAC address, rather than IP? I'll be happy limiting remote access to my phone .As an aside, how does UPnP open ports safely?
