DHCP Configuration for LAN
The Router supports three DHCP modes for the LAN. By default, DHCP service is provided using an IP pool of 192.168.1.2 – 192.168.1.254 for a total of 253 IP addresses available. The Router can also relay DHCP service from another server through the WAN port. You may prefer to disable DHCP service and DHCP relay and use a different preferred method for IP addressing on your LAN.
To disable the embedded DHCP server, select the Server and Relay Off option and click the Apply button.
Figure 3- 17. Configure DHCP service for the LAN
For DHCP service on the LAN, select the Server On option to enable DHCP service from the Router (enabled by default) and configure DHCP server parameters as follows:
DHCP Parameter | Description |
Start IP | Type in the base address for the IP pool of unassigned IP addresses. This IP |
| address must be consistent with the Management IP address of the Router. |
| Normally the Start IP address is one greater than the Management IP address. |
End IP | Type in the last address of the contiguous IP address range to be used by the |
| Router for DHCP function. Up to 253 consecutive IP addresses may be used |
| for the pool. |
Lease Time | This specifies the amount of time (in seconds) a client can lease an IP |
| address, from the dynamically allocated IP pool. |
Click the Apply button to make the changes to the DHCP settings. Remember to Save All in the Tools/System Commands menu.
