CHAPTER 23: Configuring Wireless Settings
Configuring a Secure Wireless Bridge
When switching from Access Point mode to Wireless Bridge mode, all clients are disconnected, and the navigation panel on the left changes to reflect the new mode of operation.
To configure a secure wireless bridge, follow these steps:
1Click Wireless, then Advanced.
2In the Wireless Radio Mode section, select Wireless Bridge from the Radio Role menu. The TZ 170 Wireless updates the interface.
3Click Status. Any available access point is displayed at the bottom of the Status page. Click Connect to establish a wireless bridge to another TZ 170 Wireless.
4Click Settings. Configure the WLAN settings for the wireless connection as follows:
aConfigure the SSID on all TZ 170 Wireless to the SSID of the Access Point.
bConfigure the WLAN for all TZ 170 Wireless must be on the same subnet.
cLAN IP address for all TZ 170 Wireless must be on different subnets.
For example, in the previous network diagram, the TZ 170 Wireless are configured as follows:
•SSID on all three TZ 170 Wireless are set to “myWLAN”.
•WLAN addressing for all the TZ 170 Wireless's connected via Wireless Bridge must place the WLAN interfaces on the same subnet: 172.16.31.1 for TZ 170 Wireless1, 172.16.31.2 for TZ 170 Wireless2, and 172.16.31.3 for TZ 170 Wireless3.
•TZ 170 Wireless4 must have a different subnet on the WLAN, such as 172.16.32.X/24.
•LAN addressing for all TZ 170 Wireless connected via Wireless Bridge must place the LAN inter- faces on different subnets: 10.10.10.x/24 for TZ 170 Wireless1, 10.20.20.x/24 for TZ 170 Wireless2, and 10.30.30.x/24 for TZ 150 Wireless/TZ 170 Wireless3.
•LAN addressing for TZ 170 Wireless4 must be the same as TZ 170 Wireless3.
•To facilitate Virtual Adapter addressing, the TZ 170 Wireless4 can be set to forward DHCP requests to TZ 170 Wireless3.
•When a TZ 170 Wireless is in Wireless Bridge mode, the channel cannot be configured. TZ 170 Wireless2 and TZ 170 Wireless3 operate on the channel of the connecting Access Point TZ 170 Wireless. For example, TZ 170 Wireless1 is on channel 1.
•A Bridge Mode TZ 170 Wireless cannot simultaneously support wireless client connections. Access Point services at Remote Site B are provided by a second TZ 170 Wireless (4). The chan- nel of operation is set 5 apart from the channel inherited by the TZ 170 Wireless3. For example, Access Point TZ 170 Wireless1 is set to channel 1, then Bridge Mode TZ 170 Wireless3 inherits channel 1. Access Point TZ 170 Wireless4 should be set to channel 6.
