Can anyone tell me the advantages/disadvantages of these two types of VPN?

What do you know about PPTP and L2TP?

Which machines does it run on typically?

What do you know about L2TP?

Which machines does it NOT run on typically?

Which non-Microsoft machines may support L2TP?

When was L2TP introduce on Microsoft products?

When was PPTP introduced on MS computers?

Who else (besides MS) is likely to support PPTP?

How is the encryption security different for the two?

Pptp is easier to configure, compatible with NAT devices, and can be secure
if mschapv2 is used and strong passwords are enforced [like complex and at
least ten characters. L2tp uses a stronger encryption via ipsec, creates the
tunnel BEFORE user authentication is done, and also insures intergrity and
authenticity. L2tp however will not work over NAT without the NAT-T client
and a NAT-T VPN server such as Windows 2003, and a computer certificate is
required for both the VPN server and VPN client for Windows 2000. --- Steve
