Configuring Network Connections
groov is designed to work with a network that has a Dynamic Host Configuration Protocol (DHCP)
server and a Domain Name Server (DNS). If your network has DHCP and DNS, you do not need to
assign an IP address to the
groov Box; you just plug it in and the IP address is assigned automatically.
This is the recommended method for setting up the groov Box.
However, if you need to customize your network connections for groov after the initial setup, groov
Admin provides the tools to do that.
This section includes the following topics:
• “Assigning a Static IP Address” on page 22
• “Changing the Hostname, DNS Servers, or IPv4 Gateway” on page 23
• “Configuring ETH1 for the Control Network” on page 24
• “Configuring Wireless Communications” on page 25
To set up your network, see form 2161, the Guide to Networking groov . This guide provides detailed
information on how to make your groov network more secure. It also describes how to directly
communicate with groov over the Internet using a virtual private network (VPN) or with port
forwarding (PF). A VPN is recommended because it is more secure.
Assigning a Static IP Address
If you do not have a DHCP server, you’ll need to configure a static address to either ETH0 or ETH1.
Otherwise there may be communication errors.
NOTE: If you are using a laptop computer to assign a static IP address, make sure you disable Windows’
Internet Connection Sharing (ICS). If you don’t, the laptop will act like a DHCP server and assign a dynamic
address.
You’ll need to get the following networking information from your IT department:
• IPv4 address —A unique, fixed (static) IP address.
For example: 172.18.234.1
• Netmask —Identifies the subnetwork.
For example: 255.255.225.0
• Gateway (optional)— Identifies the route to the Internet.
For example: 172.18.1.1
