C. NETGEAR VPN Configuration

C

Case study on how to set up a VPN

This appendix is a case study on how to configure a secure IPSec VPN tunnel from a NETGEAR DGND3300v2 to a FVL328. This case study follows the VPN Consortium interoperability profile guidelines (found at http://www.vpnc.org/InteropProfiles/Interop-01.html).

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.
