Table 36-2 Menu 27.1.1 IPSec Setup

FIELD	DESCRIPTION	EXAMPLE
Secure	Type the IP address or the domain name (up to 31 characters) of the	Zw50test.com.
Gateway	IPSec router with which you’re making the VPN connection.	tw
Address	Set this field to 0.0.0.0 if the remote IPSec router has a dynamic WAN IP
	address (the Key Management field must be set to IKE, see later).
Protocol	Enter 1 for ICMP, 6 for TCP, 17 for UDP, etc. 0 is the default and signifies	0
	any protocol.
DNS Server	If there is a private DNS server that services the VPN, type its IP address
	here. The Prestige assigns this additional DNS server to the Prestige's
	DHCP clients that have IP addresses in this IPSec rule's range of local
	addresses.
	A DNS server allows clients on the VPN to find other computers and
	servers on the VPN by their (private) domain names.
Local	Local IP addresses must be static and correspond to the remote IPSec
	router's configured remote IP addresses.
	Two active SAs can have the same configured local or remote IP
	address, but not both. You can configure multiple SAs between the same
	local and remote IP addresses, as long as only one is active at any time.
	In order to have more than one active rule with the Secure Gateway
	Address field set to 0.0.0.0, the ranges of the local IP addresses cannot
	overlap between rules.
	If you configure an active rule with 0.0.0.0 in the Secure Gateway
	Address field and the LAN’s full IP address range as the local IP address,
	then you cannot configure any other active rules with the Secure Gateway
	Address field set to 0.0.0.0.
Addr Type	Press [SPACE BAR] to choose SINGLE, RANGE, or SUBNET and press	SINGLE
	[ENTER]. Select SINGLE with a single IP address. Select RANGE for a
	specific range of IP addresses. Select SUBNET to specify IP addresses on
	a network by their subnet mask.
IP Addr Start	When the Addr Type field is configured to Single, enter a static IP	192.168.1.35
	address on the LAN behind your Prestige.
	When the Addr Type field is configured to Range, enter the beginning
	(static) IP address, in a range of computers on your LAN behind your
	Prestige.
	When the Addr Type is configured to SUBNET, this is a (static) IP
	address on the LAN behind your Prestige.
