but to a Port on the 127.0.0.1 interface. The SSL VPN Agent accepts the local connection and forwards the traffic through the SSL tunnel. The
Barracuda SSL VPN forwards the traffic to the destination IP and Port defined in the SSL tunnel configuration. The traffic from the Barracuda SSL
VPN to the destination IP in the network is not encrypted anymore.
SSL tunnels can be configured to only allow local connections or to allow connections directly to the remote network. It is also possible to define
the source IP address of the SSL tunnel, so that clients in the same remote network can share a SSL tunnel. The tunnel is terminated when the
session is closed or timed out.
Next Steps
To create a SSL Tunnel complete the following instructions:
How to Create an SSL Tunnel
An outgoing SSL tunnel protects TCP connections that your local computer forwards from a local port to a preconfigured destination IP address
and port, reachable by the Barracuda SSL VPN that the user is connected to. To use the tunnel, the application or browser connects to a random
listener port on the 127.0.0.1 or 127.0.0.2 localhost address. The encrypted tunnel ends at the SSL VPN, all connection beyond the SSL VPN are
not secure. If you want other computers on the same network to share a SSL tunnel, use a network IP address instead of the 127.0.0.1 localhost
address as the source address.
