The "Send All Traffic" option is also available for PPTP.

I tried the PPTP "Send all Traffic" option to see how it will work with L2TP (PPTP is much easier to setup), but as I feared it only sends all traffic after the VPN has been manually turned on. Once the iphone goes to 'standby' mode it drops the VPN. All background activity (i.e. checking e-mail) occurs as normal traffic. In addition, every time someone starts using their iPhone they have to manually re-enable the VPN. So, "Send all Traffic" doesn't really do what it says because a lot of the the iPhone traffic continues to travel outside the VPN.
I am in the process of setting up a dedicated IPSec VPN, and I will post my results when I trying to use the 'on-demand' function.
Hopefully, IPSec will work better. However, an IPSec VPN is very hard to setup... the average user cannot setup an IPSec VPN and a Certificate Authority (certificate-authentication is required to use VPN on-demand) at home in their spare time.
Apple really should do something about this. I was very impressed with the hardware encryption they included on all iPhones from the 3GS onwards. I just wish they would apply the same security mentality to their VPN offerings. I would happily pay a couple hundred bucks for an 'Apple style' all in one device that would be easy to setup/use, and be highly secure. It would be a great solution, and an easy way to hook new small businesses into the 'apple eco-system'. Come-on Apple strategic planning team... this should be a no brain-er!!!
