• The remote WAN and LAN IP addresses for one VPN tunnel endpoint will be the local WAN
and LAN IP addresses for the other VPN tunnel endpoint.
• The VPN Wizard ensures the other VPN parameters are the same at both VPN tunnel
endpoints.

Initiating and Checking the VPN Connections

You can test connectivity and view VPN status information on the FVG318 and FVL328
according to the testing flowchart shown in
A LAN, do the following:
1. Test 1: Ping Remote LAN IP Address: To establish the connection between the FVG318
Gateway A and FVL328 Gateway B tunnel endpoints, perform these steps at Gateway A:
a. From a Windows PC attached to the FVG318 on LAN A, click the Start button on the task
bar and then click Run.
b. Type ping -t 172.23.9.1, and then click OK (you would type ping -t 10.5.6.1 if testing
from Gateway B).
c. This will cause a continuous ping to be sent to the LAN interface of Gateway B. Within
two minutes, the ping response should change from timed out to reply.
At this point the VPN-tunnel-endpoint-to-VPN-tunnel-endpoint connection is established.
2. Test 2: Ping Remote WAN IP Address (if Test 1 fails): To test connectivity between the
Gateway A and Gateway B WAN ports, follow these steps:
a. Log in to the router on LAN A, go to the main menu Maintenance section, and click the
Diagnostics link.
b. To test connectivity to the WAN port of Gateway B, enter 22.23.24.25, and then click
Ping (you would enter 14.15.16.17 if testing from Gateway B).
c. This causes a ping to be sent to the WAN interface of Gateway B. Within two minutes, the
ping response should change from timed out to reply. You may have to run this test several
times before you get the reply message back from the target FVL328.
d. At this point the gateway-to-gateway connection is verified.
3. Test 3: View VPN Tunnel Status: To view the FVG318 and FVL328 event log and status of
Security Associations; go to the FVG318 main menu and select VPN > Connection Status. For
the FVL328, click VPN Status on the VPN Status/Log screen.
