Understanding and Providing Default Gateway in Windows 8

What Is Default Gateway?

Default gateway is a computer or a hardware device that is connected to a direct Internet line, and works as an intermediary to allow communication between the computers in the in network and the different network (typically the Internet).

How Default Gateway Works in Organizations?

Almost every organization has a single Internet connection which is shared among multiple users in the network. Administrators in organizations install a proxy server or a hardware firewall that has minimum two LAN ports. One LAN port is connected to the direct Internet line a.k.a. external network, whereas the second LAN port is connected to the LAN switch, which is further connected to all computers in the office network a.k.a. internal network.

LAN port of the proxy server or firewall device that is connected to the Internet is assigned with the IP address provided by the ISP. On the other hand, LAN port of the proxy server or device that is connected to the internal network is assigned with the IP address, which the administrators have specified internally.

How Default Gateway Works in Homes?

In home networks, most ISPs provide Internet modems that are easy to configure and use. Since these Internet modems also have internal (RJ-45) and external (RJ-11) ports, the IP address assigned to the internal port of the modem is used as default gateway for home computers. (Mostly the IP address assigned to internal port in such Internet modems is

Considerations While Providing Default Gateway

  • Default gateway enables communication between different networks (typically the Internet) only when appropriate DNS address is also provided to the client computer.
  • A client computer should not be specified with more than one default gateway.
  • To stop communication between a client computer and different network, removing default gateway alone can get the task done. DNS address should be left intact for effective and efficient name resolution process.
