Select
“status” option and remember the WAN IP address, enter the IP address in browser of
PC-1, if IP Camra-1 can be visited via PC-1, the port forwarding is success. And PC-2 and
PC-3 can also visit the IP Camera-1.
WAN IP address is allotted
by ISP, please make sure it’s an available WAN IP

few time, DDNS can recognize the WAN IP address of the router-1 which connected with IP
Camera-1. The WAN IP address can be searched on DDNS by domain name. Herein,
domain name substitute the dynamic IP address. If the device c
an’t be visited by IP address,
this domain name is also unavailable.
