Web Proxy Forwarding

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 you have a proxy server on your network, instead of configuring each computer to
point to the proxy server, you may move the server to the WAN and enable Web Proxy
Forwarding. 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 Son-
icWALL WAN port.
Note: The proxy server must be located on the WAN or the DMZ; it may not be located
on the LAN.
