iPhone (IOS 5.01) and ASG 8.300 "VPN connection on demand"

Hi All

I am having problems configuring "VPN connection on demand" on my ASG 8.300

Configuration:

1)I have enabled "VPN connection on demand" on my ASG and configured the relevant domains (either FQDN or internal addresses)

2)I have downloaded the certificate and imported the settings to my iphone.
3)I would expect every time I connect to the relevant URL set on step 2, the vpn connection to be launched

If I use manual connection instead of "VPN connection on demand" I can connect fine to my resources.

It also seems that other users are experiencing the same issue. Is there a known issue with this feature or I am doing someting wrong?

Thanks
