Cisco VPN stop working after upgrading to IOS 6

Hi,

seams that cisco thinks, that if they send something encrypted in chunks, they need to set the encryption flag in the header.

So if an ipsec implementation supports IKE fragmentation it has to ignore a encryption flag on these packages, i agree on that.

Maybe Cisco sometimes documents this, and tells what have driven them to do it that way.

I also wonder why apple is just using this stuff, allows this change to their client, and are not testing against common other vpn servers as cisco.

Even Microsoft tested their ipsec client heavily against strongswan.

ddwrtchris - Excellent analysis.

Have you filed a bug with Apple for this yet?

Hi,

i will, just signed up for the Developer Account, and now i try to push this info into the apple bug-report-scheme ;-)

Hi,

we have just uploaded a patch for strongswan 5.0.1, that ios 6 + 6.0.1 here:

http://wiki.strongswan.org/issues/264

Hi,

anyone knows when this will be fixed (iOS 6.0.2)?

This is really annoying!

Best regards

Thomas

Hi,

i wrote here, that it is fixed in a beta that is right now available. that is NOT 6.0.2 ;-)

But the apple robot deleted my post.

If i write the version number again, the apple robot might delete my post again, and (accodording to my click agreement i did...) i might go to jail.

It's friday night, i just came back from sports and a beer (i am german), so please take the last sentence as i mean it.

Ciao Chris

Hi,

just checked 6.0.2 on an ipad mini, bug not fixed. So you have to wait for 6.x where x is 1.

Ciao Chris

Here is the current network conditions of what works and what doesn't on iOS 5.x and 6.0.x ..

It looks like that there was a change made on how VPN works after upgrading to iOS 6.0 or higher. The only way VPN works over cellular data is to leave the Wi-Fi turned on (but not connected to a Wi-Fi NW). On iOS 5 devices VPN works over cellular data whether the Wi-Fi is on or off. Please note that we are using the IPSec VPN.

这个BUG 带给我很大的麻烦！

Hi,

We launched our new cloud networking service today (https://www.threatspike.com) so to follow up on my previous comments, if any of you guys are still having trouble with VPN access over 3G/Wifi then come give it a try and let us know if it works for you. It's free to sign up (5GB allowance) and we would appreciate your help with testing it plus any feedback you can offer!

Thanks,

Adam

Hi all!

Does anybody know if these problems have been solved in iOS 6.1.2?

If not, has Apple said anything about when they plan to solve them?

Thanks
