Hello everyone
I wonder if there is an easy guide to IPsec somewhere on the Internet. At this point, I am not interesting in the deployment of IPsec, but rather the "description" of it. Hmm.. I mean, I want to know a bit more about IPsec (and L2TP and perhaps PPTP), because right now, everything is a big mess. I get different information on different sites. One site tells me that IPsec by itself doesn't tunnel data, that it needs L2TP to do that. Then I read somewhere else that IPsec by itselft will provide a tunnel and that L2TP is unnecessary (according to that site, L2TP only provides interoperability between VPN's (when you have more than one))
Thanks in advance
