3. What is VPN (Virtual Private Networking)?

1. How do I assign an IP address to a specific computer or device?
   1. Log into your router using the "How do I log into my router?" instructions above.
   2. To look up the IP address the computer is currently using, select "Attached Devices" in the Maintenance section of the router manager left-hand navigation menu.  Note the IP address (192.168.1.x) the device is currently using.
   3. From the Advanced section of the router manager left-hand navigation menu, select "LAN Setup."
   4. Under "Address Reservation," click the Add button.
   5. Fill in the IP address (ex: 192.168.1.x), the MAC address of the device, and a name describing the device in the spaces provided.  Click the Add button to save the information.
2. How many computers or devices can be connected wirelessly to a router at the same time?

   Any number of devices can be connected wirelessly to the router; however, performance may noticeably decrease with each additional device.  Three to five devices should be able to use the same wireless connection without a noticeable decrease in network responsiveness.

3. What is VPN (Virtual Private Networking)?

   VPN gives extremely secure connections between private networks linked through the Internet. It allows remote computers to act as though they were on the same secure, local network.

   Advantages

   • Allows you to be at home and access your company's computers in the same way as if you were sitting at work.
   • Almost impossible for someone to tap or interfer with data in the VPN tunnel.
   • If you have VPN client software on a laptop, you can connect to your company from anywhere in the world.

   Disadvantages

   • Setup is more complicated than less secure methods. VPN works across different manufacturers' equipment, but connecting to a non-NETGEAR product will add to difficulty, since there may not documentation specific to your situation.
   • The company whose network you connect to may require you to follow the company's own policies on your home computers ( ! )

   VPN goes between a computer and a network (client-to-server), or a LAN and a network using two routers (server-to-server). Each end of the connection is an VPN "endpoint", the connection between them is a "VPN tunnel". When one end is a client, it means that computer is running VPN client software such as NETGEAR's ProSafe VPN Client. The two types of VPN:

   VPN Client-to-Server (Client-to-Box):

   

   VPN Server-to-Server (Box-to-Box):
