b. From the Edit menu of the Security Policy Editor, select Add, and then click

VPN Settings screen of the wireless modem router on LAN A. Choose connection
names that make sense to the people using and administering the VPN.
Note: In this example, the connection name used on the client side of the
VPN tunnel is togw_a, and it does not have to match the
RoadWarrior connection name used on the gateway side of the VPN
tunnel because connection names are irrelevant to how the VPN
tunnel functions.
d. Enter the following settings:
• Connection Security. Select Secure.
• ID Type. Select IP Subnet.
• Subnet. In this example, type 192.168.3.1 as the network address of the wireless
modem router.
• Mask. Enter 255.255.255.0 as the LAN subnet mask of the wireless modem
router.
• Protocol. Select All to allow all traffic through the VPN tunnel.
e. Select the Connect using Secure Gateway Tunnel check box.
f. In the ID Type drop-down list, select IP Address.
g. Enter the public WAN IP address of the wireless modem router in the field directly
below the ID Type drop-down list. In this example, 22.23.24.25 is used.
The resulting connection settings are shown in Figure 44 on page 94.
