	is on the Internet. Enter the IP Address that you wish to Ping,
	and click Ping
Restart Device-	Click Reboot to restart the DI-774

VPN
Pass Through-	The DI-774 supports VPN (Virtual Private Network) pass-through
	for both PPTP (Point-to-Point Tunneling Protocol) and IPSec
	(IP Security). Once VPN pass-through is enabled, there is no
	need to open up virtual services. Multiple VPN connections can
	be made through the DI-774. This is useful when you have many
	VPN clients on the LAN network.
