Re: trendnet ip camera tv-ip110w and 2wire router cant see camera from outside home network
I would like to thank you for bringing this up and I sincerely apologize for the inconvenience this issue has caused you. With regard to your concern, there are factors we would need to consider that could have blocked you from accessing the your camera from outside sources. This problem could be because of the modem or router settings specifically its firewall. Since you're able to access the camera images within your local network then that means the static IP for the camera is mapped correctly but you would need to have this IP exempted from the modem's firewall for you to be able to access this outside your network.
You would need to set the appropriate firewall ports to be opened for you to be able to access your camera outside your network. We don't really have the specific port numbers needed to be opened as you would get this information from the manufacturer of that device. If you're using a 2wire Gateway modem you can click on this link http://www.att.com/esupport/article.jsp?sid=KB401474#fbid=v51drieR4l8 and this should give you the information on how to open specific ports for the 2wire modem. Once the ports needed for the camera is opened, then this should allow you to access the camera outside your network.
If ever you don't know the port numbers needed to be opened, your other option would be to set the modem to DMZ mode. DMZ mode is opening up all the ports on the modem's firewall and thus allowing all incoming and outgoing traffic for your network. You can click on this link http://www.att.com/esupport/article.jsp?sid=KB401374#fbid=v51drieR4l8 for the steps on how to do so. We don't really recommend this setting as opening all the ports on the modem's firewall would leave your computer exposed to malicious attacks. AT&T is not responsible for potential attacks made to your computer system or damage resulting from an attack caused by opening the ports.
