Another example of the power of blogs. Based on conversations Greg Hughes and I have had on issues from each other's blogs, we have been talking on IM as well.
Yesterday, we started talking about VPN solutions. Problems we have had with Netscreen Remote, what Greg's company uses and why, etc.
The big thing that I learned was that Cisco's VPN client allows you to reroute IPSEC traffic over multiple ports as you see fit. This is important as a lot of places now block the methods that IPSEC usually uses to create a tunnel. However, these same places don't block port 80 (HTTP - how systems connect to web sites & web apps) and port 443 (HTTPS - used to communicate with secure web sites & apps). So a VPN client that can reroute IPSEC traffic over port 80 or 443 has a great advantage over those that can't.
