Routing with Linux

Routing refers to the sorting and distribution of the data packets. The main purpose of the routing is to reduce the complexity of the networks distributing the data packets to its destination. All the Windows, UNIX and Linux based operating systems support the IP routing.  You can setup Windows, UNIX or Linux a router/gateway. There is a simple method that let you make your Linux server as a router.  It requires that you system must use iptables for NAT.

When you setup Linux a router, it defines the path and sends out the data packets based on the defined paths. In the internetwork, the data is forwarded through a series of routers.  Routing in the Linux can be accomplished by manually entering the information that is required by packets to reach any part of the network.  Linux supports multiple networking devices.  There are few configuration steps that are required to setup Linux as a router.
