Disable IPSec in l2tp VPN connection configuration

[Armando110]

Hey everybody

I'm using an l2tp vpn with a disabled IPSec in XP. However I was wondering if I could do the same in Leopard. To disable it in XP I did the following:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters]
"ProhibitIpSec"=dword:00000001

What is the analogue action in mac os x?
Is it possible to do this in my iPhone?

thanks in advance

What version of OS X are you running? Plus link to the software you are talking about.

I was talking about os x inherent configuration not any external software.
