    VPN not connecting on cellular Tracfone AT&T network

    I have not been successful connecting via Tracfone (AT&T) cellular network using either the built-in iPhone VPN or OpenVPN. I am on iOS 12.1.

    Both VPN protocols work great on WiFi but not on cellular. Does Tracfone block VPN or is a special configuration needed?

    I was under the impression that VPN is not needed for cellular because the connection is already secure. But maybe that is incorrect. WiFi is a different story.

    This is less a question if it is needed but rather one of application, e.g. tunneling into the company network or home router.

    I tried 3 different ways to use VPN via the cellular network.
    1. OpenVPN to my home router : does not connect
    2. Built-in IPSec to a different home router : does not connect
    3. Cisco AnyConnect to my company's network : connects :-)

    All three of these methods work without any issues on WiFi.

    Btw, when on cellular (LTE) the VPN icon disappears. This is a well know problem since at least iOS 11.

    Can you change the port or method? (i.e., "TCP" vs. "UDP", and/or port 443 vs. 1194)?

    FWIW, I'm on ST (and before that Net10), and had no issues connecting to any VPN on UDP/1194. Maybe it's an iPhone thing, all my tablets and phones are Android.

    Thank you, that did it changing the port to 1194 for OpenVPN

    Unfortunately I cannot do the same for the IPSec home router.

    VPNs have their uses but VPN providers market them as THE security solution that solves all problems which is simply not the case. Neither is a VPN simple to use in all cases.

    IPSec uses ports 500 and 4500.
    With this website one can simply check all ports using TCP http://portquiz.net:<port>
    Is there such a simple test for UDP?
