Configuring the Advanced Settings

Please remember:

New settings can only be made after rebooting the Gigaset SE551 WLAN dsl/cable. If necessary, reconfigure the IP address on your PC (including one that is statically assigned) so that it matches the new configuration.

Configuring the DHCP server

The Gigaset SE551 WLAN dsl/cable 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 SE551 WLAN dsl/cable.

Please remember:

uIf the DHCP server for the Gigaset SE551 WLAN dsl/cable is activated, you can con- figure the network setting on the PC so that the option Obtain an IP address automatically is set. To find out how to do this, please read the section "Configuring the local network" on page 23.

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 must select this option if you want to make NAT or firewall settings using the IP addresses of the PCs, or else you must assign these PCs static IP addresses.

ìDefine the range of IP addresses which the Gigaset SE551 WLAN dsl/cable 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 (e.g. 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 on the Add button to add the entry to the list.

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

ìApply the settings by clicking OK.
