How to Set up a Private Network

A private network is one which either does not connect to the internet, or is connected indirectly using NAT (Network Address Translation) so its addresses do not appear on the public network. However, a private network allows you to connect to other computers that are on the same physical network. This is desirable when you wish to communicate with a group of other computers or share data and internet connectivity is not necessary.


Steps

1     
      Plan your network. This is probably the hardest part of setting up a network.

Draw any routers you may be using to separate major portions of your network first. Smaller private networks do not require routers, but may still use them for administrative reasons. Routers are only required if a.)Dividing your network into multiple smaller networks, b.) Allowing indirect internet access using NAT. Next, add any switches and hubs. For small networks, only one switch or hub may be necessary.
Draw boxes to represent the computers and lines connecting the devices together. This drawing will serve as your network diagram.

Although diagrams intended only for your own use may use any symbols you desire, use of industry standard symbols make this task simpler and eliminates confusion for others. Typical industry standard symbols are:
