Re: IOS IKEv2 VPN over LTE does not work anymore

kris2k · July 2018

I’ve read the recent posts about people affected by usage NordVPN complaining, but in my case, it’s my personal network and my internal users.

I’ve ran through the preliminary details and it appears that the phone is initiating a direct IPV6 tunnel that’s superseding the device’s routing table and not allowing the device to use the IPv4 or IPv6 gateways provided by the VPN tunnel (our IPSec tunnel is dual-stack) which are provided by the device’s routing table.

What’s up with this?

Any recommended IOS profile tweaks to push down?

Hi, when ipv6 is activated, I can’t use a VOIP app I’m using for my works. (Cisco Jabber). If I’m using an APN to disable ipv6 it fixed the problems instantly. I’ve already speak with « bureau of president » concerning that matters, and the problem has been fixed since October. But it seems somebody has reactivates ipv6 feature for my account. To explained furthermore, when Rogers is converting ipv4 to ipv6 they screw my app authentication and I can’t get a positive handshake from our job server because my token is not valid anymore. I’ve already trace and dig into packets to found the reason of the issue with firewalls and IT team at my work. An engineer from Rogers (back in October) was aware of this protocol translation problem.

To everyone here that is having the same problem. As of January 6, 2019 I have opened two tickets. One here on the Fido forums and one on the phone. Support & administrators will take your information, ask you for your IMEI, and create a ticket—but they will not solve the issue however courteous they are. I have a theory is because they don't have a solution yet. If you need to use VPN over LTE it may be a good idea to start considering other options.

VPN over IKEv2 (native on iOS) ➠ it connects, but all iPv4 traffic is blocked

VPN over OpenVPN (third-party app) ➠ it works using iPv6 / iPv4 dual stack

Hey @mountainsofsnow

Have you rebooted your phone after you received the message that the issue was fixed? If you did and are still having trouble, you should get in touch with the developer of the app to confirm if their app properly supports IPv6 only networks, as per Apple app standards published here: https://developer.apple.com/support/ipv6.

{Update: January 12, 2018] I can confirm that after having opened a ticket and restarted my phone, VPN (IKEv2) now works. Horay!
