The following table describes the labels in this screen.

Table 102 VPN Rules (IKE): Network Policy Edit

LABEL

DESCRIPTION

 

 

Active

If the Active check box is selected, packets for the tunnel trigger the ZyWALL to

 

build the tunnel.

 

Clear the Active check box to turn the network policy off. The ZyWALL does not

 

apply the policy. Packets for the tunnel do not trigger the tunnel.

 

If you clear the Active check box while the tunnel is up (and click Apply), you

 

turn off the network policy and the tunnel goes down.

Name

Type a name to identify this VPN network policy. You may use any character,

 

including spaces, but the ZyWALL drops trailing spaces.

Protocol

Enter 1 for ICMP, 6 for TCP, 17 for UDP, etc. 0 is the default and signifies any

 

protocol.

Nailed-Up

Select this check box to turn on the nailed up feature for this SA.

 

Turn on nailed up to have the ZyWALL automatically reinitiate the SA after the

 

SA lifetime times out, even if there is no traffic. The ZyWALL also reinitiates the

 

SA when it restarts.

 

The ZyWALL also rebuilds the tunnel if it was disconnected due to the output or

 

input idle timer.

Allow NetBIOS

This field is not available when the ZyWALL is in bridege mode.

Traffic Through

NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that

IPSec Tunnel

enable a computer to connect to and communicate with a LAN. It may

 

sometimes be necessary to allow NetBIOS packets to pass through VPN

 

tunnels in order to allow local computers to find computers on the remote

 

network and vice versa.

 

Select this check box to send NetBIOS packets through the VPN connection.

 

 

Check IPSec Tunnel

Select the check box and configure an IP address in the Ping this Address field

Connectivity

to have the ZyWALL periodically test the VPN tunnel to the remote IPSec router.

 

The ZyWALL pings the IP address every minute. The ZyWALL starts the IPSec

 

connection idle timeout timer when it sends the ping packet. If there is no traffic

 

from the remote IPSec router by the time the timeout period expires, the

 

ZyWALL disconnects the VPN tunnel.

Log

Select this check box to set the ZyWALL to create logs when it cannot ping the

 

remote device.

Ping this Address

If you select Check IPSec Tunnel Connectivity, enter the IP address of a

 

computer at the remote IPSec network. The computer's IP address must be in

 

this IP policy's remote range (see the Remote Network fields).

Gateway Policy

 

Information

 

Gateway Policy

Select the gateway policy with which you want to use the VPN policy.

 

 

Local Network

Local IP addresses must be static and correspond to the remote IPSec router's

 

configured remote IP addresses.

 

Two active SAs cannot have the local and remote IP address(es) both the same.

 

Two active SAs can have the same 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.

Address Type

Use the drop-down list box to choose Single Address, Range Address, or

 

Subnet Address. Select Single Address for a single IP address. Select Range

 

Address for a specific range of IP addresses. Select Subnet Address to

 

specify IP addresses on a network by their subnet mask.
