First off my skills in advanced networking are somewhere between beginner and intermediate, speak slowly please.
I work for a AV automation company and we use EdgeRouter Lites, EdgeRouter PoEs and EdgeRouters for almost all our installations. I find it useful to have VPN access setup to make it easier to reach devices inside the network remotely (Power Conditioners, Audio Equipment, Touchscreens ect). Up until this point I was configuring PPTP access, now I am to understand this is a very weak approach and worst of all for us, dropped support in iOS10 and Seirra.
So what should I use? Looking at the configuration in iOS10 seems my options are IKEv2, IPSec and L2TP. But what is the best option given the Ubiquiti products we use and how do I configure? Usually I'd do a google search or look though the ubnt forums. But this time there’s so much information and back and forth discussion that I don't know where to begin.
Thanks for the help.
