PLANET ICA-3550V - Manual (Page 76)

Some ISPs block access to port 80. Be sure to check with your ISP so that you
can open the appropriate ports accordingly. If your ISP does not pass traffic on
port 80, you will need to change the port the camera uses from 80 to
something else, such as 8080. Not all routers are the same, so refer to your
user manual for specific instructions on how to open ports.
Enter valid ports in the Virtual Server section of your router. Please make sure to check the box
on this line to enable settings. Then the device can be accessed from WAN by the router’s WAN IP
Address.
By now, you have finished your entire PC configuration for this device.
