Please check www.sitecom.com for up to date drivers & utilities, manuals and support 6.2.2 DHCP Relay Configuration Some ISPs perform the DHCP server function for their customers’ home/small office network. In this case, you can configure this device to act as a DHCP relay agent. When a host on your network requests Internet access, the device contacts your ISP to obtain the IP configuration, and then forward that information to the host.
Sitecom ADSL2+ Modem DC-227 6.3 DDNS Settings Each time your device connects to the Internet, your ISP assigns a different IP address to your device. In order for you or other users to access your device from the WAN-side, you need to manually track the IP that is currently used. The Dynamic DNS feature allow you to register your device with a DNS server and access your device each time using the same host name. The Dynamic DNS page allows you to enable/disable the Dynamic DNS feature.
