Installed version 2.0.17 this morning and everything working beautifully and finally tonight had a chance to try my Iphone6S with the WI FI off to see if I could connect and I cannot connect from my Iphone 6S on ATT LTE system. It does not discover the FLEX6300? I must have something not right in the router? I tried opening ports 4993 and 4994 to the main computer but that didn't work. Anyone have a quick fix it is an XFINITY Router Dual Band XB3 Modem. It worked with the VPN. Any assistance would be appreciated.
