CHAPTER 11: Configuring Web Proxy Settings
Configuring Automatic Web Proxy Forwarding
SAlert: The proxy server must be located on the WAN; it can not be located on the LAN. To configure a Proxy Web sever, select the Network > Web Proxy page.
1Connect your Web proxy server to a hub, and connect the hub to the SonicWALL security appliance WAN port.
2Enter the name or IP address of the proxy server in the Proxy Web Server (name or IP address) field.
3Enter the proxy IP port in the Proxy Web Server Port field.
4To bypass the Proxy Servers if a failure occurs, select the Bypass Proxy Servers Upon Proxy Server Failure check box.
5To send proxy requests from the OPT interface as well as the LAN interface, check the Forward OPT/DMZ/WLAN Client Requests to Proxy Server checkbox.
6Click Apply. Once the SonicWALL security appliance has been updated, a message confirming the update is displayed at the bottom of the browser window.
Bypass Proxy Servers Upon Proxy Failure
If a Web proxy server is specified on the Network > Web Proxy page, selecting the Bypass Proxy Servers Upon Proxy Server Failure check box allows clients behind the SonicWALL security appliance to bypass the Web proxy server in the event it becomes unavailable. Instead, the client’s browser accesses the Internet directly as if a Web proxy server is not specified.
Forward OPT/DMZ/WLAN Client Requests to Proxy Server
By default, client requests coming in through the OPT interface are not forwarded to the Proxy Server. To send OPT/DMZ/WLAN client requests as well as LAN client requests, check the Forward OPT/ DMZ/WLAN Client Requests to Proxy Server checkbox.
