My iOS device is still running iOS 5, but it's now getting to the point that
too many apps or their updates require iOS 6. The primary reason for my
delay so far is reported problems with iOS 6 and Cisco's VPN.

Judging from the VPN application I use for my computer, Sonic is using
a Cisco VPN infrastructure (not proof, I know ^_^), so I just wanted
to know if anyone else on iOS 6 is having any problems with Sonic's VPN.

Technical note on what the problem is (post from astaro.org):
The IPsec client in iOS 6 sends IKE packets split up into IKE fragment payloads
in some situations. This is a bit hacky workaround to get around some broken
NAT gateways that don't handle IP fragments properly. iOS 6 sends the IKE fragment
payloads regardless of whether its IKE peer announced support for this unpublished
IKE extension or not. A clear case of iOS being a bit of a bully here. =)

So, does iOS 6's VPN Client work with Sonic?

Thanks.

It works fine for me on my iPad. In general, the iOS 6 network stack seems to be a little less robust than iOS 5's, so I end up rebooting the iPad several times a week. (I normally just close the cover, putting it to sleep, but since iOS 6, I have to shut down completely every second or third day.)

Note that after I upgraded from iOS 5 to iOS 6, several network settings appeared to get corrupted. I could not get VPN to work at all, and several of my WiFi access points acted flaky. I reset all networking, which wiped out all the configured WiFis and the VPN. Once reconfigured, they started working ok, and as long as I shut it down regularly, everything's just fine.
