If there is another DHCP server running on your network (on another router), you must
disable one of the DHCP servers.
If Enable DHCP Server is selected, selecting this option causes the systems on the VT2142

If Enable IPS DNS,SNTP is selected, the ISP may also transmit other data to the computers
on the VT2142 LAN, including, but not limited to, the time, log, cookie, print, NTP, and WINS
servers.
Sets the first IP address assigned by the DHCP server, in
Start IP
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).
Sets the final IP address assigned by the DHCP server, in dotted-decimal format. It cannot
End IP
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.
Sets the time, in seconds, that a network computer remains connected to the voice gateway
Lease Time
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).
If selected, the voice gateway forwards requests and responses between the computers on
Enable DHCP Relay
your network (the DHCP clients) and the DHCP server you chose to use for your network.
If you select Enable DHCP Relay, type the IP address of the DHCP server in dotted-decimal
Relay IP
format.
If selected, you must carefully configure the IP address, Subnet Mask, and DNS settings of
