Voice Gateway with Router
If you use the Voice Gateway to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Voice Gateway. You can get the information from your ISP.
A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.
A DHCP server can either be a designated PC on the network or another network device, such as the Voice Gateway. By default, the Voice Gateway’s Internet Connection Type is DHCP (obtain an IP address automatically).
The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.
For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet. This is a dedicated,
By default, a DHCP server (on the LAN side) is enabled on the Voice Gateway. If you already have a DHCP server running on your network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Voice Gateway, see the Router - LAN Setup section in “Chapter 5: Using the
dynamic ip address: a temporary IP address assigned by a DHCP server.
dhcp (dynamic host configuration protocol): a protocol that lets one device on a local network, known as a DHCP server, assign temporary IP addresses to the other network devices, typically computers.
