Which VPN access approach has the best security, is easiest to set-up and will work if you dial-up using AOL as your ISP?

ADDITIONAL INFORMATION:

For a remote PC, you offer 3 ways for that PC to use VPN to access a 550/600/660 VPN device:

- Sentinel IPSec sw
- Native IPSec in Windows XP or 2000
- PPTP

What are the pros and cons of these different approaches so I can pick the best one for each situation?


RESPONSE:

PPTP is the easiest of all three. It is free, built into all Windows and is very easy to setup. It works well behind a NAT / firewall that supports PPTP pass-thru.

The Sentinel IPsec and Windows IPsec clients are used because some customers do not like Microsoft and they don't think PPTP is secure enough for a VPN.

All the three clients should work with AOL as long as it uses a public IP address.
