Configuration Profile
The configuration in this appendix follows the addressing and configuration mechanics
defined by the VPN Consortium. Gather necessary information before you begin
configuration. Verify that the firmware is up to date, and that you have all the addresses and
parameters to be set on both sides. Check that there are no firewall restrictions.

Step-by-Step Configuration
 To configure a VPN tunnel:
1. Use the VPN Wizard to configure Gateway A (DGND3800B) for a gateway-to-gateway
tunnel (see
Add a Gateway-to-Gateway VPN Tunnel on page 125), being certain to use
appropriate network addresses for the environment.
The LAN addresses used in this example are as follows:
a. For the connection name, enter toGW_B.
