Revision Date Description
A 07/02/03 Initial release
B 08/19/03 Added RF560VPN
C 03/19/04 Changed to document the RF760VPN/RF660VPN/RF600VPN only
D 11/17/04 & 01/25/05 Changes for software 3.20 and 3.21
The examples on the following pages illustrate:
1. RF760VPN / RF660VPN / RF600VPN connected to another RF760VPN / RF660VPN / RF600VPN
through a VPN tunnel configured for Manual Mode.
2. RF760VPN / RF660VPN / RF600VPN, behind a NAT box, doing IPSec Pass-Through in Manual Mode
to another RF760VPN / RF660VPN / RF600VPN.
The RouteFinder software is pre-installed on the RF760VPN, RF660VPN, and RF600VPN RouteFinders. The
RouteFinders use the same software, version 3.21. Initial configuration is required in order for you to run the
RouteFinder software and begin operation.
The browser-based interface eases VPN configuration and management. The VPN functionality is based on IPSec
and PPTP protocols and uses 168-bit Triple DES encryption to ensure that your information remains private.
IMPORTANT:
Caution: Use a safe Password! Your first name spelled backwards is not a sufficiently safe password; a password
such as xfT35$4 is better.
