You'd also need to have the SNWL logs to knoe why it doesn't complete phase 2

Also you'll need more info on the SNWL side, including what version of OS
they are using

Lastly, if they have a halfway decent version, you will *not* be able to
use the GroupVPN SA, as that will require the SNWL VPN Client!...

Good luck!
