Delete: Click it to remove one mapping item.
Double click one item; you can change the corresponding mapping information. See Figure 4-68.
Important:
When you are setting the router external port, please use 1024~5000 port. Do not use well-known
port 1~255 and the system port 256~1023 to avoid conflict.
For the TCP and UDP, please make sure the internal port and external port are the same to
guarantee the proper data transmission.
