If you are in a location that does not have a conventional ‘local area network’ (LAN), such as in a home or small office setting, then you may be wondering what the difference is between awan networking and traditional IP networking. You may be wondering how can technology can benefit your company or home-based business. Basically, awan technology utilizes the same technology as your company’s existing network that routes your data packets to their respective destinations. A network has become the backbone of how we communicate with each other and how the world shares information.
The idea behind awan networking is that a computer must maintain two separate but connected networks. One network connects to the WAN router, while the other network connects to the WAN interface router. In order for this to work, the WAN router advertises itself to the rest of the world as an authoritative source. On the other hand, the WAN interface router acts as a router for a local area network. These routers do not respond to broadcasts from other routers, but they do forward data from their clients to other computers within their own LAN using a TCP/IP based technology called layer 2 encapsulation.
Basically, the idea is that two independent computers can be connected through a WAN router with a TCP/IP based encapsulated technology. Each computer is in its own private WAN port and each computer has a unique IP address. In order for all of these computers to function together, they form a cascaded router network address, or ARN.
Wan side subnet
The two IP addresses, or levels, are what identifies the location of each computer on the network. If you had a single WAN address, then it would be easy for a WAN router to send information from one computer to another over the Internet, but it is much harder for two computers to associate with each other. In order for this to happen, the WAN side must configure a gateway between itself and the internal LAN subnet. This is also known as a private firewall, or WAN gateway.
To allow both computers on a WAN side subnet to connect to each other, the WAN router has the ability to create address families. Address families are collections of IP addresses where each IP address corresponds to a port number. In the case of a WAN trunking service, the primary network has a common default gateway that is connected to a series of secondary networks. This allows for a connection to be made between any number of computers as long as there is an available WAN port.
One of the advantages of the private WAN trunking is that a router doesn’t have to know the IP address of the clients and because of this it will use the default gateway IP address. The second advantage of this type of service is that if the primary WAN router ever suffers from a major outage, the secondary WAN router can take over this function. In other words, when the primary WAN goes down, the secondary WAN router will take over. While some people may find this to be a security risk, other people see it as more of a convenience feature that allows people to use their WAN connection whenever they want without having to juggle with a bunch of wires.
Another advantage to using a private WAN trunking system is that you don’t have to deal with the WAN routers of your ISP. In fact, with WAN trunking you never have to deal with another network connection at all. If you’re like most businesses, the last thing you want to do is make sure that your customers are able to connect to the Internet, and you don’t want to have to deal with dealing with the routing table for a private IP network. The only thing that you have to worry about with WAN trunking is ensuring that your company’s IP address is clear on the secondary network.
Of course, if you’re going to be using a private WAN connection, you will also want to consider a firewall. Some WAN providers such as Gigabit Fibre Optix now offer firewall systems that allow you to customize filtering and blocking properties for each subnet. In fact, some of the newer firewalls include built-in support for forwarding through ports, which means that you can configure a policy for all outgoing traffic to match up with a corresponding policy for incoming traffic. With this additional address range, you can effectively block any unauthorized subnets while allowing all of your internal traffic through.
