I have 3 Netgear FVS318v3 routers in different offices. I am trying to setup the routers in each office to have 2 VPN tunnels (one to each of the other 2 offices). I have the VPN tunnel working between office A and B. However the problem I'm having is that I can't get either of them to connect to C. Below is a description of how its connected.

LAN -> FVS318 -> DSL Modem (in bridge mode) -> Internet -> DSL Modem (bridge mode) -> FVS318 -> LAN

Each of the offices have a dynamic IP so I have setup dyndns.org to give a domain name to each of them. Below are the policy details from office A. The settings are the same in office C, except for changes to the IP ranges and end point.

IKE Policy
Name : yellow
Direction: Both
Exchange mode: Main Mode
Local Identity Type: WAN IP Address
Remote Identity Type: Remote WAN IP
Encryption Algorith: 3DES
Auth Algorithm: SHA-1
Auth Method: Pre-shared Key
DH Group: Group 2 (1024 Bit)
SA Life Time: 28800

VPN Auto Policy
Name: yellow
IKE Policy: yellow
Remote VPN  Endpoint: FQDN
Address: [my dyndns.org domain name]
SA Life Time: 28800 (Seconds)
IPSec PFS: Disabled
Local IP: Subnet address (192.168.1.0 / 255.255.255.0 )
Remote IP: Subnet address (192.168.3.0 / 255.255.255.0 )
AH Auth: Disabled
ESP Encryption: Enabled (3DES)
ESP Auth: Enabled (SHA-1)
NetBios: Enabled

When I attempt to initiate the connection from office A I see the following:
[2008-10-08 06:08:01][==== IKE PHASE 1(to x.x.x.x) START (initiator) ====]

This is where it stops. No mater which end I connect from it always does the same thing.

1) Start with seeing if you can bet A->  or B-C workig.

maybe the problem is at the C site.
Do you have the laetst firmware updates ?

Did you check the netgear site to see how to do this ?

I have also been wondering if something is wrong with the router in office C. The connection between A-B is working, but I have not been able to get A-C or B-C working.

As for the firmware all 3 are running version 26, the latest version is 27. I am going to upgrade office C to the latest version in a few hours.

I updated the firmware in office C and all of the links started working. Not sure what the problem was but at least its fixed now.
