IOS IKEv2 VPN over LTE does not work anymore

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. Smiley 

 

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.

Hey @ken20kca,

 

Just to clarify, are you using your phone to tether or is your work computer connected to your Home Internet?

Hi FidoClaudia,

 

I used my phone to tether, so my work laptop can VPN back to office PC for work. It has always work since I join Fido, but all of suddent it stop working like about a month ago. My work require me to VPN back to office for emergency response. I have done test with my coworker's phone(using Bell), and it was working. So there seems to be an issue on Fido's end. Thx

The issue has been resolved. It seems Fido is dropping IKE traffic from my VPN client. As a work around, I had to restrict the size of the first ISAKMP packet sent from my VPN client. (Sonicwall)
