Enable DHCP | If selected, the DHCP server on the voice gateway assigns IP addresses to the computers and | ||||||||||
Server | 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 | |||||||||
|
| 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 | |||||||||
|
| 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 |
| format. |
Server and Relay | If selected, you must carefully configure the IP address, Subnet Mask, and DNS settings of |
Off | 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. |
