Configuring the Advanced Settings

Configuring the DHCP server

The Gigaset SX541 WLAN dsl has a DHCP Server for which the factory setting is active. As a result, the IP addresses of the PCs are automatically assigned by the Gigaset SX541 WLAN dsl.

Please remember:

uIf the DHCP server for the Gigaset SX541 WLAN dsl is activated, you can configure the network setting on the PC so that the Obtain an IP address automatically option is set. To find out how to do this, please read Section "Configuring the Local Network" on page 21.

uIf you deactivate the DHCP server, you will have to assign a static IP address for the PCs using the network settings.

ìTo activate the DHCP server, select On.

ìIf the DHCP server is active, you can define a Lease time. The Lease time determines the period for which the PCs keep the IP address assigned to them without changing them.

Please remember:

If you select the Never expires option, the IP addresses are never changed. You should select this option if you want to make NAT or firewall settings using the IP addresses of the PCs; otherwise you have to assign these PCs static IP addresses.

ìDefine the range of IP addresses that the Gigaset SX541 WLAN dsl should use to automatically assign IP addresses to PCs. Define the First issued IP address and the Last issued IP address.

ìYou can define the name of a domain (Windows workgroup) in the Domain name field.

Assigning Static IP Addresses to Individual PCs

Even if you have activated the DHCP server, you can still assign individual PCs a static IP address (for example if you are setting up these PCs for NAT functions).

ìEnter the MAC address and the name of the PC in the Device name field.ìEnter the IP address you wish to assign to the PC in the field below.

ìClick the Add button to add the entry to the list.

ìClick the Delete button to delete the entry from the list.

ìApply the settings by clicking OK.
