Automatic Proxy Forwarding (Web Only)

A Web proxy server intercepts HTTP requests and determines if it has stored copies of the requested Web pages. If it does not, the proxy completes the request to the server on the Internet, returning the requested information to the user and also saving it locally for future requests.

Setting up a Web proxy server on a network can be cumbersome, because each computer on the network must be configured to direct Web requests to the server.

If there is a proxy server on the SonicWall appliance’s network, you can move the appliance between the network and the proxy server, and enable Web Proxy Forwarding. This forwards all WAN requests to the proxy server without requiring the computers to be individually configured.

The proxy server must be located on the WAN or DMZ; it cannot be located on the LAN.

To configure a Proxy Web server

1. Navigate to the NETWORK | System > Web Proxy page.

2. Type the name or IP address of the proxy server in the Proxy Web Server (name or IP address) field.
3. Type the proxy IP port in the Proxy Web Server Port field.
4. To bypass the Proxy Servers if a failure occurs, enable Bypass Proxy Servers Upon Proxy Server Failure. This option allows clients behind the 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.
   
5. To force clients on public zones to use the proxy server as well, enable Forward Public Zone Client Requests to Proxy Server.
6. Click Accept.

After the appliance has been updated, a message confirming the update displays.

Confirm the Description and Schedule.
