The conspicuous dissimilarity between Firewall and Proxy Server lies in Firewall's function to impede unauthorized individuals from establishing connections and accessing your network. Conversely, Proxy Server's primary objective is to operate as a relay to facilitate connections between two points.
In practice, Proxy Server can also function as a Firewall if programmed for such purposes. Proxy Server can scrutinize the packets being sent and received, subsequently filtering and allowing the data to pass through based on pre-established rules.
In terms of functionality, Firewall can be likened to a chokepoint between the Local network and the Public network within the Internet system. Outgoing traffic is permitted, whereas unwanted incoming traffic is often blocked. These configurations can also be found in Proxy Servers.
The presence of Proxy Servers across both Local and Public networks is not widespread. These are referred to as open Proxies. Similar to Firewall, Proxies can be easily circumvented through an alternate route.
As mentioned earlier, a Firewall acts as a lock to screen connection requests to safeguard the internal network from the Public Network or the Internet system. Although Proxy Servers are utilized for various purposes, the most common remains anonymity for Internet users.
Since Proxy Servers establish connections with the desired websites, user IP addresses and other identifying information remain undisclosed. Users often utilize Proxy Servers to browse restricted websites within the network system.
If your Admin restricts access to and viewing of websites like Facebook, using a Proxy Server allows you to circumvent those rules by employing an indirect route.
In summary, the difference between Firewall and Proxy Server is:
1. Firewall blocks connections while Proxy Server facilitates connections.
2. Proxy Server can function as a Firewall.
3. Firewall typically serves as an interface between Public (public network) and Private network, whereas Proxy Servers can also exist within the Public Network on both sides.
4. Firewall is utilized to safeguard an internal network against attacks, whereas a Proxy Server is used to conceal identity and bypass restrictions.
With this article, you can easily differentiate between Firewall and Proxy Server, right? Through this, you can grasp a more suitable, convenient, and secure connection method.
Both Firewall and Proxy Server are readily available on the Windows operating system, however, for effective connection through Proxy Server, you will need to use software such as Ultrasurf to change your IP address. Refer to how to use Ultrasurf to achieve the best results.
