Salve ecco un ottimo sito dove trovare molti how-to ed esempi per vari profili di VPN … Come riportato nel sito:

VPNC is pleased to introduce its documentation profiles for IPsec. The purpose of these profiles is to help users understand how to set up their systems and to understand the vocabulary used in their system documentation. As more vendors adopt these profiles, we believe that the interoperability of IPsec implementations will generally increase.
