Wireless Configuration
Figure 9: Default SSG 20-WLAN Configuration
By default, the wireless0/0 interface is configured with the IP address of
192.168.2.1/24. All wireless clients that need to connect to in the Trust zone must
have an IP address in the wireless subnetwork. You can also configure the device to
automatically assign IP addresses in the 192.168.2.1/24 subnetwork to your devices
with DHCP.
By default, the wireless0/1 - wireless0/3 interfaces are defined as Null and do not
have IP addresses assigned to them. If you want to use any of the other wireless
interfaces, you must configure an IP address for it, assign an SSID to it, and bind it
to a security zone.
For more information about WLANs, refer to “Wireless Interface” in the Concepts
and Examples ScreenOS Reference Guide .
Wireless Network Configuration
Wireless networks consist of names referred to as Service Set Identifiers (SSIDs).
Specifying SSIDs allows you to have multiple wireless networks reside in the same
location without interfering with each other. An SSID name can have a maximum of
32 characters. If a space is part of the SSID name string, then the string must be
enclosed with quotation marks. Once the SSID name is set, more SSID attributes
can be configured.
The SSG 20-WLAN device allows you to create up to 16 SSIDs, but only 4 of them
can be used simultaneously. You can configure the device to use the 4 SSIDs on
either one of the transceivers or split the use on both. For example, 3 SSIDs
assigned to WLAN 0 and 1 SSID assigned to WLAN 1. Use the
set interface
wireless_interface wlan { 0 | 1 | both } CLI command to set the radio transceivers
on the SSG 20-WLAN device.
To set the SSID name netscreen open , allow the SSID to be open to all users, bind
the SSID to the wireless0/0 interface, and use both radio transceivers, do either of
the following:
AUX 0 / 0 10 /100 AUX 0 /0
