Transparent proxy

The transparent proxy provides the same service function as the traditional proxy, but its "transparent" implementation depends on the default route and firewall redirection strategy, so it is more suitable for serving LAN hosts than for clients in INTERNET.

Configure SQUID to support transparent proxy

The default configuration of the SQUID service does not support transparent proxies, so you need to adjust the settings. For SQUID services above version 2.6, transparent proxies can be supported by adding a "transparent" option to the http_port configuration line.
