I am trying to access security cameras over the internet but am having some trouble. The cameras sit on a local network and connecting to them by IP works fine on the local network. I have a Zyxel USG 20w and have setup up firewall rules to forward WAN traffic to the camera's static IP address on port 7000. I've double checked the static IP of the cameras and port and it's all correct.
Connecting to the cameras is done using this format URL:Port/webviewer.htm. When I ping the URL it doesn't respond, because it's not set to respond to ICMP, but it does show me the correct public IP address so I know it's going to the right place. I've only set up 2 properties with the Zyxel USG 20 and the other property had a DYNDNS url and I got that one working fine using firewall rules. Does anyone have experience with this router or one that's similar in regards to forwarding traffic to a LAN Security camera? I'm also wondering if I need to forward traffic to port 80.
