Configuration: Basic Advanced TCP/IP

Wireless

Enable DHCP
Server

If selected, the

DHCP

server on the voice gateway assigns IP addresses to the computers and

other

hosts

on your network, if they have DHCP enabled (see

“Configuring TCP/IP”

on

page 53). By default, the voice gateway DHCP server is enabled.

If there is another DHCP server running on your network (on another router), you must disable
one of the DHCP servers.

Start IP

Sets the first IP address assigned by the DHCP server, in dotted-decimal format. It must be
greater than the IP address value of the voice gateway. For example, if the IP address of the
voice gateway is 192.168.15.1 (default), the starting IP address must be 192.168.15.2 (or
higher).

End IP

Sets the final IP address assigned by the DHCP server, in dotted-decimal format. It cannot
exceed the subnet limit of 254. For example, the default is 192.168.15.254. If the DHCP server
runs out of DHCP addresses, users cannot access network resources. If this happens, increase
the End IP (to the limit of 254) or reduce the Lease Time.

If you change Start IP or End IP, be sure they are in the range for specified by the Subnet IP
Address and Netmask. For example, if the voice gateway IP address is 192.168.15.1 (the
default) and you set Start IP and End IP to 192.168.0.2 and 192.168.0.100, respectively,
computers with DHCP enabled cannot communicate with the voice gateway.

Lease Time

Sets the time, in seconds, that a network computer remains connected to the voice gateway
using its current assigned IP address. At the end of this time, the DHCP server renews the lease
or assigns the computer a new IP address. The default is 3600 seconds (1 hour). The maximum
is 999999 seconds (about 278 hours).

Enable DHCP Relay If selected, the voice gateway forwards requests and responses between the computers on your

network (the DHCP clients) and the DHCP server you chose to use for your network.

Relay IP

If you select Enable DHCP Relay, type the IP address of the DHCP server in dotted-decimal
format.

Server and Relay
Off

If selected, you must carefully configure the IP address, Subnet Mask, and DNS settings of
every

host

on your network. Do not assign the same IP address to more than one host. Your

voice gateway must be on the same subnet as the other hosts.
