How to set up a proxy server


What is a proxy?

A ‘proxy’ means a substitute. To the computers on the local network, a proxy server is another way to connect directly to the web by giving the user a different IP address. There are several different types of proxy servers. For example, a web proxy server keeps copies of recently accessed web pages on your hard disk.

When you navigate to a page, the proxy accesses the cached version if it’s up to date. This is faster than downloading static files from the site.

Why people use proxy servers

You may be tempted to disable the proxy settings in your browser to view sites your boss would rather you didn’t during work hours. However, to ensure that everyone on the network uses the proxy to access the internet, system administrators often block all access to the internet at their firewall, except traffic coming from or going to the proxy. So to access anything outside the local network, you must use the proxy.

Forcing everyone to use the proxy gives system administrators great control over what their users can access. The same principle can be used at home by parents and those simply keen to bolster security.

If you find unexpected access attempts in a firewall’s log file from inside a proxy-protected network, they’re probably coming from malware that doesn’t know how to test for a local proxy and has tried to go directly online.

Public vs private proxy

While there are many different types of proxies, as we’ve mentioned, they can be sorted into two categories: public proxies and private proxies. As the name suggests, public proxies are free and open to the public, while private proxies are used by only one person.

Because of the influx of users, public proxies are often far less effective than private ones. They’re also more dangerous, as the proxy operator can see your web traffic and potentially hijack your network.

How to set up a proxy server on Windows

Setting up a proxy on Windows is fairly easy, as newer Windows software automatically detects proxy settings.

To set up a proxy on Windows 10, simply head to your Settings screen and open the Network and Internet section. From there, click on the Proxy tab and choose from the list of available proxy settings.

For Windows 8 users, the steps are slightly different. Start by opening the PC Settings application and click on the Network Proxy icon. You’ll see a selection of proxy servers to choose from. Enter the proxy’s URL and then save your settings.

If your Windows network can’t automatically detect your proxy, you can set it up manually by entering the proxy’s specific IP address and the port number of the proxy. Your provider should have this information if you’re using a private or business proxy.

How to set up a proxy server on Mac

Mac users can also take advantage of easy-to-use proxy services. To set up a proxy server on an Apple Mac, start by opening your System Preferences and clicking on the Network icon.

From there, scroll down and click the Advanced button. On the right, click on the Proxy tab. You’ll see a list of different proxy protocols.

You can check the Auto Proxy Discovery box if you want your Mac to deem whether a proxy is necessary and configure its settings automatically.

To set up a proxy manually, select the type of proxy you want to use and type its corresponding address and port number in the open fields. If the proxy is password-protected, check the Proxy Requires Password box and enter the username and password in the boxes provided.

Once you select a proxy, enter the address and port number in the space provided, click OK and you should be set.
