Interfaces
This section of the VPN 3002 Hardware Client Manager applies functions that are interface-specific,
rather than system-wide.
You configure two network interfaces for the VPN 3002 to operate as a VPN device: the private interface
and the public interface. If you used Quick Configuration as described in the VPN 3002 Hardware Client
Getting Started manual, the system supplied many default parameters for the interfaces. Here you can
configure them explicitly.
The VPN 3002 includes some IP routing functions: static routes, DHCP, and PPPoE. You configure static
routes, the default gateway, and DHCP in the IP Routing section; see the Configuration | System | IP
Routing screens. PPPoE requires no further configuration than supplying a username and password in
the Public Interface parameter.
Configuration | Interfaces
This section lets you configure the private and public interfaces.
• Private is the interface to your private network (internal LAN).
•
Public is the interface to the public network.
Configuring an Ethernet interface includes supplying an IP address and subnet mask, and setting speed
and transmission mode.
Note Interface settings take effect as soon as you apply them. If the system is in active use, changes might
affect tunnel traffic.
The table on the Configuration | Interfaces screen shows all installed interfaces and their status.
