		network traffic meets all criteria, then a VPN tunnel will be created.
Local IP		The drop-down menu allows you to configure the source IP address of the
		outbound network traffic for which this VPN policy will provide security.
		Usually, this address is from your network address space. The choices are:
		• ANY for all valid IP addresses in the Internet address space
		• Single IP Address
		• Range of IP Addresses
		• Subnet Address
Remote IP		The drop-down menu allows you to configure the destination IP address of
		the outbound network traffic for which this VPN policy will provide security.
