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?
Solved! Go to Solution.
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.
-have tried rebooting phone, reinstalling VPN profiles, etc.
VPNs works perfectly fine on WiFi but runs into issues over LTE. Worked perfectly fine over LTE just days ago so assuming something changed?
I am using a iPhone 8 with iOS 12.4. My VPN type is L2TP.
No problem with the server or setup, the VPN works fine if I am using WiFi.
But it fails with fido LTE network. it is said "server did not respond".
If I setup a hotspot and let my iPad to connect to the internet over iPhone's LTE network, the VPN also works.
Anyone know how to fix it? thank you
It is been log time since these ip4/ ipv6 stack troubles on certain iphones.
I would like to know please:
1) Was the issue completely resolved, assuming latest iOS ?
2) People like me were taken a special care by a PM and a tweak against the IMEI.
If changes were done at Fido for specific issue (put on "old stack" etc.) - were these changes reverted after all is fixed?
For iPhone users, the iOS update at 12.2 seems to fix this issue while for Android users, they'd need to disable iPv6. However, if you're still experiencing difficulties past this, you can reach out to us and we'll have our support teams further look into this for you.
