After upgrade to iOS8 can not use IPV6

[hmolina]

Hi!

After upgrade to iOS8, I can not connect to IPv6 servers (v.gr: ipv6.google.com).

Thanks in advance.

Mmm.

Using MyIPs app, the utun0 interface shows the correct IPv6 address, but can not ping to that address from my servers.
Route problem?

TIA.

There is iOS 8 VPN unstable issue (both for OpenVPN and L2TP) for normal IPv4 connection mentioned in another thread.

Not sure if it is related to your problem.

Could you try it at iOS 7?

If it is ok when under iOS 7, it could be Apple's iOS 8 issue as I have no problem at all when using iOS 8 beta 5.

Hi!

Thanks for your reply.

Up 1.03 it was working well with iOS7 (I did not do any IPv6 specific test with 1.04 and 1.05 with iOS7).

I can made a ping form my VPN server to my OpenVPN Connect client, and it works well.

So, I think the problem is when sets the routes.
I have 2 VPN:
1st: Routing all the traffic through the VPN, using:
push "redirect-gateway def1".
The traffic do not works!

2nd VPN: Routes only my company traffic, I define several routes maps using commands like:
push "route-ipv6 fec0:0:0:1040::/64"
All the IPv6 traffic which not uses the VPN works.

In both cases, i can ping my client from the server, but can not ping form other machines, nor connect from my Client to other machines.

The IPv4 traffic works well.

T.I.A.

Would suggest you test it under iOS 7 for your set up as I have told my customers not to upgrade iOS 8 until Apple fix it later.

I have one iPad 2 running iOS 7.1.2 and all the VPN protocols (PPTP, L2TP and OpenVPN) are working normally.

I even tried to upgrade the subject iPad 2 to iOS 8 GM and only PPTP was working.

So, I rolled back it to 7.1.2 and everything is back to normal.

It should be the Apple problem as I also have one iPhone 4S running iOS 8 beta 5 and everything is working!
