There are many different ways to circumvent online restrictions and censorship. While VPNs are the most popular option and tool to do so these days, they are not the only option. Before today’s polished, ready-to-go market options were so readily available, proxies were also one of the main ways that people bypassed internet censorship. In fact, it is noteworthy to know that a lot of techs that are put together as part of a more outstanding general category of “VPN” today are actually proxies. An excellent example of this is the so-called “Shadowsocks VPN,” which, in fact, is a proxy.

As time went by, both VPNs and proxies have become the target of restrictions and attacks themselves. So, both technologies have gone to further lengths to come up with new ideas and solutions in order to fix these issues. While in the VPN world, we have solutions like site-to-site VPNs, proxies have come up with newer solutions such as reverse proxy and, of course, the subject of today’s post, the proxy chain.

But what exactly is a proxy? How is proxy chaining done, and what are its main pros and cons? Stay with me to get the answer to all of these questions, as well as a quick guide on how to establish your own proxy chain!

What is a Proxy?

Most people either have a vague definition of a proxy or otherwise conflate its definition to overlap with other definitions like a VPN. A proxy is essentially made up of a server that acts as an intermediary force or a “gateway” between you and the internet connection. So when you are connected to a proxy server, you are essentially operating a three-way connection that is made up of your computer, the proxy server, and the destination you are navigating to. Let’s say there is a website that has limited your access to its domain. How exactly would a proxy help you? 

When you are connected to a proxy server and try to reach a website, your data packets are initially sent to the proxy server instead of the destination; then, this server will act on your behalf and will send the data over. When the response comes back from the blocked domain, it also returns to the proxy server, which will then replicate it for you. The main difference from a VPN here is in the fact that a VPN allows you to fully assume their server and use it as if it’s your own, whereas proxies are more like middlemen.

What is a Proxy Chain, and Why Do We Need It?

Proxy chaining is a more elaborate process that involves using a proxy server to proxy into another server and doing this multiple times in order to create enough masking and packet processing and request layers to ensure your anonymity. A proxy chain has two primary use cases: first, to make the user anonymous, and second, to make them bypass restricted blockages that can detect and block regular proxies. Remember when I said when you use a proxy, it’s like a three-way internet connection with the proxy as the middleman? Well, a chained proxy is the exact same thing, with the notable difference that we now have a number of servers in-between as opposed to a single one. 

As the number of these intermediary servers increases, it becomes increasingly complex for the firewalls to detect your proxy and block it. So you will be able to bypass internet censorship easier. This increase in proxy servers also makes for much much more efficient masking of online identity. Let’s say you do not want to be tracked online; naturally, cracking and tracking a single proxy server is much easier than five or six. But even with server proxy servers chained, you will not be entirely anonymous, and a skilled enough admin can track you, so keep that in mind.

Advantages and Disadvantages of Proxy Chaining

Using a proxy chain has its own set of advantages and disadvantages you need to consider before deciding to go on and create a multi-layered proxy chaining operation of your own. Here are three key advantages and three disadvantages of proxy chaining. I’ll start with the advantages and then work my way to the disadvantages.

Proxy Chaining Advantages


As the number of proxy servers increases, so does the operational capacity of each server to process the packets and send them back to the user, coupled with a more efficient caching process that happens at the moment; proxy chains are a speedy method of bypassing restrictions and remaining anonymous on the web. 


As mentioned earlier, the higher the number of intermediary proxy servers, the harder you will be to track and the easier it will be to stay anonymous on the web. Each proxy server in a proxy chain is a security mask for the server preceding it, couple this with an encryption protocol, and it will be tough to track you down. This is why hackers almost always use proxy chains when in operation.

Efficient Caching

Cache memory is used to store the critical access data of recently visited domains. This stored data is then used to facilitate quick access and also to remember user preferences on a website. A higher number of proxies are better at caching, and therefore, you get to access cached websites faster and more efficiently. 

Proxy Chaining Disadvantages


Managing a large number of dependable servers as part of a single connection operation will take a lot of work. You will be personally responsible for managing all the servers and making sure everything runs smoothly, and sometimes, this can be too much for one person.

High Dependability 

As a single one of your proxy servers stops working, so does the entire proxy chain operation. Therefore proxy chaining is highly dependent on every single server, and should one of them go out; you need to find a replacement. 

Potential Costs

The more complex your proxy chain is, the more servers you are going to need. The more servers you use, the more potential costs of bandwidth and server maintenance will be. If you have enough hardware lying around, you can manage some of them, but especially if you are going to use foreign servers as proxy servers, then the costs of these servers begin to pile up.

What is IPtables?

Users primarily use a Linux environment to use and operate servers. This is primarily due to the fact that Linux distros are designed for web development and other coding endeavors. IPtables is a program designed for Linux environments that enables us to set up a host of different networking rules, such as firewalling and proxy chains.

Proxy Chaining Using IPtables: A Short Guide

In this section, I will teach you how to use IPtables to forward packets through different servers and create a proxy chain.


Make sure you have an original proxy server in place, then check that your IPtables version has yet to have any rules in place for pre-routing and post-routing sections.

Step 1: Enable IP Forwarding

Enter the following commands in order to enable IP forwarding, which will serve as the primary tool of our chaining operation:

echo "1" > /proc/sys/net/ipv4/ip_forward

Now, enter this command to add a rule that allows you to forward packets from the IP address of your VPS to (example destination), using port 1111:

# iptables -t nat -A PREROUTING -p tcp --dport 1111 -j DNAT --to-destination

Finally, enter this command to enable the masquerade:

iptables -t nat -A POSTROUTING -j MASQUERADE

Step 2: Enable Specific Network Traffic Forwarding (Optional)

If you want to direct data from a specific source to another host, enter the following command:

# iptables -t nat -A PREROUTING -s -p tcp --dport 1111 -j DNAT --to-destination

And if you want to perform chaining from a whole network to another than put in this command:

# iptables -t nat -A PREROUTING -s -p tcp --dport 1111 -j DNAT --to-destination

Step 3: Repeat the Process as Needed

This is all you need to do to chain one server to another to create a chained proxy. Repeat this process by changing the variables to match your additional servers to keep adding servers to your proxy chain.

Proxy Chain vs VPN: Which One is for You?

The proxy chain vs VPN debate is always a topic of conversation in security. Both operations are really good at private web browsing and changing your IP address. However, a VPN is more readily accessible, has less maintenance than a chained proxy. It helps you prevent your ISP’s spying and provides better overall protection through encryption. So VPN is a more suitable overall choice with better cost efficiency.

Stealth VPN Protocol - Unblockable VPN Technology 🙅

There are a set of niche use cases that can make an outstanding choice in a user’s preference for a proxy chain. For starters, your privacy is better protected using a proxy chain. If privacy and anonymity are your number one priority, then without a doubt a proxy chain is way more efficient than a VPN. Also, in cases where you want to bypass internet censorship that has also engulfed your ordinary VPNs and proxies, a proxy chain works with a better overall performance. While there are Obfuscated VPN options that can pull this off, a chained proxy is as viable, if not more.

Lastly, a proxy chaining option can easily be used along several other instances at the same time, allowing you to switch and alter your server as the need dictates. This is usually done by extensions like Omega Switch. This option is useful for keeping anonymity by rapidly changing your proxy server, and is not possible with a VPN.

Can A Proxy Chain be Used With Reverse Proxy?

Yes. A reverse proxy model is used in cases of bypassing strict internet censorship. You can also use this model to increase privacy and efficiency, similar to a standard proxy model.

Is Proxy Chain More Secure than VPN?

A proxy chain is better at making your IP address harder to track, while a VPN is better at making your data harder to track and encrypted. However, you can use an encryption protocol as part of your proxy to also make this happen on your proxy chain.

How Many Proxies Can be Used in Proxy Chain?

There’s no limit to this; however, as the number of servers piles up, your speed may be affected. Overall, between 4 to 6 is the balanced and recommended number.

Will Proxy Chaining Make me Fully Anonymous?

No. Although proxy chaining does make you incredibly hard to track, a dedicated enough tracker can link one proxy after another to finally reach the logs where your actual IP address is stored.

Is Tor a Proxy Chain?

Yes. If you find the process of establishing a proxy chain operation from scratch to be too much, you can use Tor which is essentially a complicated and efficient pre-configured proxy chain.
