2. Route Mapping: user PC logs into router configuration menu,
gets into "Port Mapping" (router management authorization may
be required); refer to below picture, DO NOT tick "Do not apply this
rule", from first frame under "External port", input any number
from 1~65535, but preferred to be set at more than 10000 like
10200 so there will be less port conflict possibility. From "Internal
IP", input the camera1's IP address 192.168.1.179, from first frame of
"Internal Port", input 3478, (all cameras use this same port
number). "Protocol" and "Mapping Line" can be default, from
"Note", input "Camera 1's mapping port" or something to
understand.
