Is it even possible to host a VPN server and have it accessible via WAN using an IPhone tether?
I can successfully connect and access local devices via VPNs hosted on my Slate router from the internet if I forward ports on my home router. When I switch the same router to tether mode and connect to an Android phone, IOS Phone, or Verizon hotspot device (not officially listed as a ‘modem’), I cannot connect. I forwarded all the ports I think are necessary on the Verizon device, and even turned on DMZ to the Gl-Inet router’s IP. I suspect what I am trying to do is only possible with an approved modem.
