Explain the Difference Between Lan and Wan Firewall Rules

What is the Difference Between Lan and Wan Firewall Rules

If you are trying to start a home office or increase the security of your business network, it is important that you have a solid understanding of what different types of firewalls are. In this article, I will compare Lan and Wan firewall rules to give you an idea of what each one can do for you.

What is a Lan and a Wan Firewall Rule?

Lan firewall rules are rules that are only applied to the local area network that the device is connected to. Wan firewall rules are rules that are applied to all of the networks on which your device is connected, including wired and wireless networks.

Examples of Free Lan Firewall Rules

Lan firewall rules are typically created for private network connections, such as on a home router. For example, on a router that has three (3) LAN connections, the lan firewall rule on the router would allow traffic for IP addresses 10.0.0.1 to 10.0.1.2 and only block access from IP address 10.1 to 10.2

Examples of Paid Lan Firewall Rules

In the world of networking, security is a big buzzword that has been around for decades. One of the most common terms in this industry is firewall, which creates a barrier between your network and the internet. This is similar to a wall built between your house and the street. When it comes to firewalls, you have two types: paid and free.

Examples of the Wan Firewall Rule

A Lan Firewall rule is usually called a “Gateway” rule. This is because it lets traffic leave the LAN, but not enter. A Wan firewall is designed to enable you to configure your ruleset based on the type of traffic that is traveling through your WAN interface. You can use this feature to separate different types of traffic for any purpose.

How to Manage Your Traffic on Free or Paid Firewalls

Most companies use a combination of free and paid firewalls. The difference comes in when you have to manage traffic between private networks and the company’s network. Lan rules are good for traffic that is destined for one of your LANs, while wan rules are good for traffic that is destined for the Internet.

Protocols on an Encrypted Connection

Lan and Wan firewalls use different protocols to determine if it’s okay to allow or block traffic on a connection. The difference comes down to the nature of the encryption that is being used. Lan firewalls work by detecting a specific port number, while Wan works by examining a connection as a whole. If your firewall is set up correctly, you should be able to detect the type of encryption being used and make decisions accordingly.

Conclusion

The difference between the two types of firewall rules is that a LAN rule can be applied to a specific network or a portion of a network. A WAN rule, on the other hand, can be applied to a wide range of networks and cannot be restricted to a single network or portion of the network.
