2.3.2 Configuring the tunnel interface
Each SSL connection (like a tunnel) is bound to a tunnel interface. It is necessary to assign the tunnel
interface to the same virtual router as the incoming (clear text) traffic. This way, when a packet comes to
the firewall, the route lookup function can determine the appropriate tunnel to use. The tunnel interface
appears to the system as a normal interface, and the existing routing infrastructure can be applied.
In our example, the interface “tunnel.10” will be used for the VPN SSL traffic.
