HTTPS tunnel - better and easier than VPN.

The Barracuda HTTP tunnel provides an easy and convenient method for remote use of Internet/Intranet software. Your standard Internet software is configured to use the HTTP tunnel proxy for access to your company's LAN. In addition, the tunnel allows collaboration from access points not accessible to VPN solutions such as from behind external company firewalls.

The Barracuda HTTPS tunnel acts as a SOCKS, HTTP, and HTTPS proxy server. The HTTPS tunnel allows you to use your Internet applications such as your browser anonymously, despite firewalls. The Barracuda HTTPS tunnel also supports a direct tunnel for protocols that do not support proxying; such as TELNET, FTP, VNC, and most Internet protocols.

Why even consider using IPSec and VPN when a HTTPS Tunnel can do 99% of what you can do with IPSec. Unlike VPN/IPSec, The HTTPS tunnel is very easy to configure and use.
