the policy for that VPN tunnel.

1. Log in to the ADSL Modem Router.
2. Open the DG834G management interface and click on VPN Status to get the VPN Status/Log
screen (Figure 8-34).

tunnel. If there is a problem with the VPN tunnel, refer to the log for information about what
might be the cause of the problem.
