A common configuration for home, small office, or cyber cafe networks is one in which a PC contains 2 network cards with one card used to provide network routing for the local PCs and one card used to connect to the internet.
In this case of 2 (or more) network cards, the Proxy Server automatically defines one card address to be the LAN side and the other network card address to be the WAN side but it is unable to determine which is which. You must tell it in the options dialog box.
If you wish to offer proxying or muling services to the outside world you will need to enable the WAN side in the options dialog box.
These are the addresses that the Proxy Server will listen on. It must be from the addresses bound to the network cards on the host running the Proxy Server.
If you are not sure about safety, you should or managing the access control lists you should use only address that are local to your LAN.
These are the ports that the Proxy Server will listen on. The check boxes besides each port entry tell the Proxy Server whether or not to activate the particular service. The default entries are usually satisfactory although if you decide to run the MULE service it may conflict with a web server since they will both normally share the same port (80). In this case, we recommend you move the web server to a different port (81) for example. If someone wishes to reach your web server in this case, they will have to modify the address from http://someaddress/ to http://someaddress:81/.
This is the port that you configure your browser to to enable the browser to filter through the Proxy Server.
