What Is A Proxy Server? | PCMag
A proxy server is a computer system or router that functions as a relay between client and server. It helps prevent an attacker from invading a private network and is one of several tools used to build a firewall.
The word proxy means “to act on behalf of another, ” and a proxy server acts on behalf of the user. All requests to the Internet go to the proxy server first, which evaluates the request and forwards it to the Internet. Likewise, responses come back to the proxy server and then to the user.
Proxy Servers Provide Anonymity
Like a virtual private network (VPN), a proxy server hides the user’s IP address when accessing the Internet. See VPN and TLS.
Address Translation and Caching
The proxy server is a dual-homed host with two network IP addresses. The address on the outbound side is the one the Internet sees. Proxies are often used in conjunction with network address translation (NAT), which hides the users’ IP addresses on the internal network. Proxy servers may also cache Web pages so that the next request for that page can be retrieved much faster. See NAT and proxy cache.
Anonymous proxy servers let users surf the Web and keep their IP address private (see anonymous proxy). Although not specifically called proxies, Internet email (SMTP) and the Usenet new system (NNTP) are somewhat similar because messages are relayed from sender to recipient. See firewall.
Application Level and Circuit Level
“Application-level” proxies or “application-level gateways” are dedicated to specific content such as HTTP (Web) and FTP (file transfer). In contrast, a “circuit-level” proxy supports every application (see SOCKS).
Forward and Reverse Proxies
In this definition, the proxy servers are “forward proxies” that hide the details of the clients from the servers. However, proxies can also reside at the website to hide details from the clients (see reverse proxy).
A Proxy Server in a LAN
In this example, the proxy server functions as a firewall in the public side of a company network, which is called the “demilitarized zone” (see DMZ).

General Router DNS Setup for Smart DNS Proxy
Following Smart DNS Proxy DNS setup instructions is only needed one time. Once you finish the initial DNS setup you won’t be needing to take the same steps anytime. Your connection will work automatically *anytime!
— — — Smart DNS Proxy setup is very simple and can be done with any router/modem brands. The main idea is to change your Router/Modem DNS IPs to Smart DNS Proxy IPs. Then, you are all set. Please find general router DNS setup instructions for Smart DNS Proxy below: 1. Log into your router Admin Panel. You can find this information in your router/modem instruction book. In general, you can get access to your router admin panel with entering one of the following to your Internet Browser (Chrome, Internet Explorer, Safari, Firefox, Opera, etc) on your PC/mobile device. In your router/modem instruction book, the correct IP should be provided. Once you enter the correct router/modem IP address in your Internet Browser, it will open your router admin panel. 2. Enter your router Admin Username and Password. You can find this correct information from your router/modem instruction book. In general, most router/modems are using “admin” or “root” for default username, and “admin”, “password” for default passwords. Once you enter the correct credentials, you will enter the admin panel of the router/model. 3. Find DNS Settings and Change them to Smart DNS Proxy DNS IPs. Once you log in, please find a section where it says for DNS Settings. There it may be selected as Automatic or there may show some DNS IPs already. Automatic means, your router is getting the DNS IPs from its network device (Mostly from your Internet Service Provider). If it’s not in Automatic mode and you see some DNS IPs, please take them a note. So in case if you want to revert back you can change it back to the old IPs. (In general, you can always select Automatic and your new settings will be reversed). Ok now you need to change your router DNS IPs to Smart DNS Proxy IPS as following: In Most routers, it says PRIMARY Server and SECONDARY Server, or DNS SETTINGS 1, DNS SETTINGS 2. Either way simply updates them as following DNS IPs. The list of IP addresses of our DNS servers can be found on our DNS Server List here: the closest DNS servers to your physical location. Select the closest server to your physical location as Primary. Then select the 2nd closest server to your physical location as Secondary server.
4. Now Save your new settings. In general, you should find the SAVE button down the page. You may also see the Apply button. Click on SAVE and APPLY. 5. Restart your Router. It’s always suggested to have your router restart once after the new DNS Settings. And that’s it. Your router is set up properly. We now suggest you to LOG INTO your Smart DNS Proxy MyAccount section and make sure that you see 3 green ticks. You can visit this page from your PC Internet Browser (your PC should be connected to this router via wireless or wired). If your IP shows not active, simply click the UPDATE IP button and you are all good:). Attention Make sure to RESTART your Router! * Remember whenever your PC/Router IP changes, our service will stop working for you. You will need to LOG INTO Smart DNS Proxy and UPDATE your IP address so that our system could check your IP address and add your new IP to our database. Then, you will be able to continue using our service. If this is the first time you set up, we also suggest that you log in with your PC to our site from the same Wired/Wireless network to show our system your IP address.

How to Set Up a Linksys Router As a Proxy Server – Small …
When configuring your network within your home or office, it is important to know what tools to use. This involves understanding the terminology employed and how certain technologies work. A Linksys router, for example, can function as a proxy server for your network. This involves setting up the router to act as a gateway for local traffic. This means that, should the network service your local office, the Linksys router can serve as a proxy for all the computers connected. Proxy Servers Proxy servers serve as online services that allow computers an indirect connection to other network services, such as the Internet and other networked computers. Network traffic travels through the proxy server, which then may or may not perform some additional task before routing traffic. For example, the proxy server might save often-viewed web pages or censor web traffic directed to particular computers on the Internet. In any case, the server will be the only way in which certain computers can access Internet traffic. Transparent Proxy Servers The most basic proxy servers are “transparent” proxy servers. While some servers cache web pages for later viewing, or hide user information while the Internet is accessed, a transparent proxy server simply directs traffic between network computers. This means that computers on the network can see each other, share data and access shared resources through local IP addresses or computer names. On the local network, there may be little or no privacy in a transparent proxy system. Accessing the Linksys Administration Routers function as transparent proxy servers. In order to set up a Linksys router to function properly in this capacity, you must first access its administration panel. The administration panel is Web-accessible, meaning that you can access it from a Web browser on a computer attached to the local network. Simply enter “192. 168. 1. 1” in your browser’s navigation bar to navigate to the login page of the router. The default factory settings of Linksys routers leave the user name blank and use “admin” as the password. Configuring the Router as a Proxy Once in the administration window, click the “Setup” tab and ensure that the “Obtain an IP Automatically” is selected from the drop-down menu. Also, click on the “Administration” tab to enter a new user name and password for future access. Finally, click on the “Advanced Routing” tab, followed by the “Show Routing Table” button to display all computers using the router as a transparent proxy. Using these IP addresses, you can connect to any other computer on the network as long as they allow communications in some form, such as through SSH or FTP. References Writer Bio G. S.
