TCP/IP
IP Address | IP address for the ADSL Wireless Firewall Router, as seen from |
| the local LAN. Use the default value unless the address is al- |
| ready in use or your LAN is using a different IP address range. In |
| the latter case, enter an unused IP Address from within the |
| range used by your LAN. |
Subnet Mask | The default value 255.255.255.0 is standard for small (class "C") |
| networks. For other networks, use the Subnet Mask for the LAN |
| segment to which the ADSL Wireless Firewall Router is attached |
| (the same value as the PCs on that LAN segment). |
DHCP Server | ∙ If Enabled, the ADSL Wireless Firewall Router will allocate |
| IP Addresses to PCs (DHCP clients) on your LAN when they |
| start up. The default (and recommended) value is Enabled. |
| ∙ If you are already using a DHCP Server, this setting must be |
| Disabled, and the existing DHCP server must be re- |
| configured to treat the ADSL Wireless Firewall Router as the |
| default Gateway. See the following section for further details. |
| ∙ The Start IP Address and Finish IP Address fields set the |
| values used by the DHCP server when allocating IP Ad- |
| dresses to DHCP clients. This range also determines the |
| number of DHCP clients supported. |
| See the following section for further details on using DHCP. |

What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request.
∙The client request is made when the client device starts up (boots).
∙The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address.
