If you have a proxy server on your network, instead of configuring each computer to point
to the proxy server, you can move the server to the WAN and enable Web
ProxyForwarding. The SonicWALL automatically forwards all Web proxy requests to the
proxy server without requiring all the computers on the network to be configured.
Configuring Web Proxy Relay
1. Connect your Web proxy server to a hub, and connect the hub to the SonicWALL WAN
port.
Note: The proxy server must be located on the WAN or the DMZ; it can not be located
on the LAN.
2. Log into the SonicWALL Web Management Interface. Click Advanced at the left side
of the browser window, and then click the Proxy Relay tab at the top of the window.
3. Enter the name or IP address of the proxy server in the Proxy Web Server field, and
the proxy IP port in the Proxy Web Server Port field. Click Update.
4. If the Web proxy server is located on the WAN between the SonicWALL and the
Internet router, add the Web proxy server address in the SonicWALL Intranet tab.
Click the Intranet tab at the top of the window.
5. To bypass the Proxy Servers if a failure occurs, select the Bypass Proxy Servers
Upon Proxy Server Failure check box.
Note: The Intranet settings tab is displayed on page 98.
6. In the Intranet tab, enter the proxy server's IP address in the Add Range field.
7. Select Specified address ranges are attached to the WAN link and click Update.
Once the SonicWALL 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 in the Proxy Relay tab of the Advanced section,
selecting the Bypass Proxy Servers Upon Proxy Server Failure check box allows
clients behind the SonicWALL 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.
