OpenVPN Support Forum

I was trying to find a way to connect to my router remotely and the only way I knew was through the ASUS router app, but the app needed the Web Access on WAN enabled and that sounded too risky. A member of another forum mentioned to use VPN which my router was capable of doing, was a better option so I did my research, turn on the server, exported the certificate to the iPhone and like magic, I was able to connect to my router. I wanted to take this opportunity to thank the guys at OpenVPN for creating such an easy app to use and configure. I was able to connect through my cellular network, will I have trouble if I use my work wifi or a public wifi?
