The NO.1 entry in Figure 3-66 indicates: TCP data received on port 12856 of the WAN port in
the Router will be forwarded to port 12856 in 192.168.0.101 server in LAN.
Note:
● When using UPnP function, make sure the UPnP is enabled for the Router, and the operating
system and applications in the host support UPnP service.
● As some Trojan and viruses can open the specific port using UPnP service resulting in hacker
attack on the host, be careful of using UPnP service.
