[Openswan Users] Windows vpn clients

[Norbert Wegener]

Hello Andreas,
if you configure a vpn connection on a windows client via DUN, Windows 
by default creates l2tp/ipsec connections, with ipsec in transport mode.
This mode is disabled in strongswan by default and can only be activated 
via a compiletime switch. Therefore I wonder,
what is the recommended way to setup a vpn with a window client and a 
strongswan server?
Do I need a third party client for the windows system?
Regards
Norbert
