In this tutorial, we will redirect local network traffic to the internet through the Squid proxy. Only the device working as a proxy needs internet access; the rest of the devices will connect through it. Since all connections pass through the proxy, its implementation allows us to filter accesses. Usually, in this scenario, the proxy device has two network interfaces. A network card is used for the local network, while the second is used to access the internet.
All connection petitions requested by local network devices are passed through the internal network card and forwarded to the external network card if traffic is allowed. Additionally, Squid proxy works as a cache server by saving data obtained from different petitions, increasing the traffic speed when similar petitions are done. In this case, only new or modified data will load; the rest will remain stored in the server.
Usually, several cache servers are implemented, and they are structured as trees. Set up a proxy manually Open Settings. Click Proxy. In the Address field, type the IP address.

If the content-length is larger,the server connection is closed and the user receives an error message from Squid. Some responses don't have Content-length headers. In this case, Squid counts how many bytes are written to the client.
Once the limit is reached, the client's connection is simply closed. SquidFaq ConfiguringSquid squid-cache wiki. Search Search:. User Login. From 3.
