I had done many ways like restarting my router, calling my ISP to confirm that my ip is a public ip, recheck my ip address and change it using my dyndns host but all still doesn't work . And right now i still cant access my router and cctv

Do you mean you cannot access your router and cctv suddenly ? – Lawrence – 2013-12-11T07:12:49.487

Please describe how are you trying to access the devices - which protocol, do you use IP address or DNS name, from where (I guess from Internet). How do you have address translation (NAT) configured on the router. How does it behave? Did it work before? What has changed? – pabouk – 2013-12-11T10:00:49.603
