Proxy Server Port: 3128
The proxy server acts as a go between for websites and web browsers. It works by listening on a specific port number on the proxy server. Web browsers have to know which port it is, or they won't know how to connect to the proxy server.
Identification:
Some port numbers are popular. Port 3128 is the default port for the Squid proxy server. Port 8080 is the default port for the Microsoft ISA proxy server.
Usage:
Once the proxy server administrator configures a port number for the proxy server, the web browser is configured to use the proxy server's port number and host name to browse the web.
Considerations:
Proxy server administrators do not use the default ports, because hackers know and attack them.
Alternative:
A PAC file (Proxy Auto Configuration) is often used by web browsers to automate configuration. A web browser fetches the PAC file to determine the proxy server's port number and other configuration.
