Secure remote access to your PC or LAN from any Internet-connected computer. The Barracuda HTTPS tunnel allows you to encrypt arbitrary TCP connections inside SSL. The HTTPS tunnel allows you to secure non-SSL aware services such as TELNET, FTP, VNC, etc., by having the HTTPS tunnel provide the encryption. The HTTPS tunnel can also be used, for example, to tunnel traffic out from behind a restrictive firewall/proxy that only allows outgoing HTTPS web connections. 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.
