IOS IKEv2 VPN over LTE does not work anymore

[kris2k]

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?

Hey everyone!

A little bit of an update for this.  

For Apple devices: 
Apple has released the latest iOS 12.0.1 software which may resolve issues for certain remote/VPN Apps using the IPv6-only connections.

If you’re experiencing this issue, please update to iOS 12.0.1 (or newer) and test again.

A possible workaround for Android devices only:
Modify the APN “ltemobile.apn” to IPv4 instead of the default IPv4/IPv6 in the phone settings, under Wireless & Networks - Cellular Networks - Access Point Names.

Power cycle the device and test the VPN connection again.

If the issue persists, please note the date and time of the failure and let us know so we can send you a PM to look closer into this with you.

Hello, I'm having a very similar issue but it's more to do with accessing a security camera app. Please help. I'm on iOS 12.1.4. Worked fine for a long time. Sometime in early-mid 2018, it stopped. Can access fine via WiFi.

Thank you.

I'll send you a PM shortly

I have same issue trying to connect to my VPN over LTE.  Not something I do very often, but important to test when having VPN problems.  Took some time to spot the issue but my iphone X (12.1.4) is getting an ipv6 address when on LTE. 

The built-in ios client is apperently using this address and the VPN won't connect.

When I tether my PC (ipv4) to the phone, and then initiate the VPN, that works fine.

Something changed on Fido side, this used to work...

Thanks
