DESCRIPTION

 

Priority

Enter the priority (between 0 and 255) of this interface when the area is looking

 

 

for a Designated Router (DR) or Backup Designated Router (BDR). The highest-

 

 

priority interface identifies the DR, and the second-highest-priority interface

 

 

identifies the BDR. Set the priority to zero if the interface can not be the DR or

 

 

BDR.

 

 

 

 

Link Cost

Enter the cost (between 1 and 65,535) to route packets through this interface.

 

 

 

 

Passive

Select this to stop forwarding OSPF routing information from the selected

 

Interface

interface. As a result, this interface only receives routing information.

 

 

 

 

Authentication

Select an authentication method, or disable authentication. To exchange OSPF

 

 

routing information with peer border routers, you must use the same

 

 

authentication method that they use. Choices are:

 

 

Same-as-Area- use the default authentication method in the area

 

 

None - disable authentication

 

 

Text - authenticate OSPF routing information using a plain-text password

 

 

MD5 - authenticate OSPF routing information using MD5 encryption

 

 

 

 

Text

This field is available if the Authentication is Text. Type the password for text

10.9.2 WLAN Add/Edit Screen: WEP Security

WEP provides a mechanism for encrypting data using encryption keys. Both the ZyWALL and the wireless stations must use the same WEP key to encrypt and decrypt data. Your ZyWALL allows you to configure up to four 64-bit or 128-bit WEP keys, but only one key can be used at any one time.

"WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-available software. It is strongly recommended that you use a more effective security mechanism. Use the strongest security mechanism that all the wireless devices in your network support. For example, use WPA-PSK or WPA2-PSK or WPA or WPA2 if your wireless devices support it. If your wireless devices support nothing stronger than WEP, use the highest encryption level available.

To configure and enable WEP encryption, click Network > Interface > WLAN > Add (or Edit) to open the WLAN Edit screen. Select WEP as the Security Type. The following screen shows the WEP security fields.
