VPN (Virtual Private Network) ports must first be added to the edit area of a
device before they can be configured. For more information about adding and
deleting VPN ports, see Chapter 6 - VPN Ports and Tunnels.
Once you have created a VPN port, you may access the IPX Routing: VPN
Configuration Dialog Box by clicking on IPX Routing under the VPN port’s
icon.
A VPN port is a virtual port which handles tunneled traffic. Tunnels are
virtual point-to-point connections through a public network such as the
Internet. All packets sent through a VPN tunnel are IP-encapsulated packets,
including AppleTalk, IPX and even IP packets. This encapsulation is added
or removed, depending on the direction, by “Tunnel Partner” devices. Once a
packet reaches the remote Tunnel Partner, the TCP/IP encapsulation is
stripped off, leaving the original protocol. The unencapsulated packet is then
handled according to the VPN port’s protocol configuration settings.
Networks connected via a tunnel will communicate as if they are on the same
network, even though they are separated by the Internet.
v Note: Remember that you must set up both ends of every tunnel. Therefore,
you must repeat this setup with the remote device.
