ADVANCED LAN
The ADVANCED LAN options are for users that wish to change the LAN settings. D-Link does not recommend changing these settings from factory
default. Changing these settings may affect the behavior of your network.
UPnP is used for much popular Audio Visual software. It allows the auto discovery of your device on the network. If you feel that UPnP is a security
concern we provide you with the option to disable it here. Block ICMP Ping should be enabled so that the router does not respond to malicious
Internet requests. Multicast streams are used by advance network functions like IPTV and distributed by your ISP.
To access the ADVANCED LAN setting window, click on the Advanced LAN button in the ADVANCED directory.
