Two environmental problems:
Fixed IP environment 1. The network, through the router mapping, mapping PC1 remote desktop, so that you can remote management PC1 from other place. But if the Intranet via IP access to the network to connect to the remote desktop, unable to connect, because can use it before, later changed in a router, not line, the original is sharp Czech NBR1000E replaced by NBR2600G now, don't know whether such access to the router what corresponding function??

Environment 2. Mobile phone client access remote monitoring, now most of the business enterprise inside monitoring have mobile phones on the access function, at the time of an installation, found that if the phone is connected to and monitor the same wireless network, cannot connect to the monitor, the same set, if the phone connection is the other network can access the monitoring, can also use mobile networks, is as long as not in the same network can access, monitor software use was also the way to port mapping,

The above two kinds of environment, should be the same problem, is in the network of the this IP networks outside mapping equipment can't access,
Confused for a long time, hope to talk about a great god,
