I have a question regarding opening ports 80 and 443 through the firewall so that I can check my CCTVs when I am away. It used to work very well until some recent changes.
- Before: Copper connection and BT Smart Hub (the one with a horizontal bar).
- Now: Fibre connection and BT Smart Hub 2 (the one with a big circle in the front).
My settings remain unchanged. Here they are.
(1) Under Home > Advanced settings > Firewall > Port forwarding, I have:
rule_name cctv_server 80 80 80 80 TCP
rule_name cctv_server 443 443 443 443 TCP
(2) Under Home > Advanced settings > Firewall > Configuration > Firewall, I have:
Default
(3) Under Home > Advanced settings > Broadband > Dynamic DNS, I have:
Dynamic DNS: ON, Username: ..., Password: ..., Confirm Password: ..., Service: NoIP, Use Multiple Hosts: NO, host: foobar.ddns.net
I use NoIP DDNS service. Something is working. (3a) My account at noip.com does update my IP correctly. When the IP of my BT Smart Hub 2 changes, NoIP has it updated correctly. It is 86.167.xxx.xxx presently. (3b) When I ping foobar.ddns.net, it returns 86.167.xxx.xxx which indicates DNS lookup works.
(4) There has been no other changes to my cctv_server or existing devices in my home network.
Unfortunately, I cannot restore the old settings from the previous hub, apparently because they are different models. Any help is welcome.
