Rather, you manually enter all the authentication and key parameters. You have more control over the process, however the process is more complex and there are more opportunities for errors or configuration mismatches between your DG834G and the corresponding VPN endpoint gateway or client workstation. Using Auto Policy to Configure VPN Tunnels You need to configure matching VPN settings on both VPN endpoints. The outbound VPN settings on one end must match to the inbound VPN settings on other end, and vice versa. See "Example of Using Auto Policy" on page 8-41 for an example of using Auto Policy.
