Yeah, that's what I was unsure of. The question in my head was "is it possible you NEED a vpn connection to get network access". I always thought of it as more of a supplemental/nice-to-have thing. Never used it seriously outside of "connect to work from home".
That actually happens quite often. Until a few months ago, the only way to get online via my university's wireless was to use a VPN - and it would be well possible that this is someone's only internet connection. After installing from a core cd, one would want to go oline.
c) openswan/openvpn/vpnc
I am not sure why we have openswan there and not ipsec-tools, but I don't know much about ipsec anyway, I always failed in using it. openvpn is a free VPN solution similar to ipsec, but much easier to set up (for both server and client). It is widely used for VPNs. vpnc is an open source replacement for the Cisco VPN Client. You can connect to Cisco 3000 and similar concentrators. The protocol is based on ipsec, but has some proprietary enhancements in authentication. This is what my university uses.
