With UPnP (Universal Plug and Play) function, the host in LAN can request the Router to
carry specific port forwarding, thus the external host can access the internal host for
resources. For example, the MSN Messenger under Windows XP and Windows Me can
utilize UPnP in video and audio communication, thus the function restricted by NAT can
restore its normal use. Enable UPnP to help support applications that would not otherwise
work behind a Router. Both UPnP Internet Gateway Device and NAT Traversal are
supported.
