sohocctv 0 Posted December 27, 2013 Hi, we have an old software/PC DVD that runs under WinXP. The GUI says it is a DiscoverEye system. We have no problem accessing the cameras from our internal network but when we tried to access from the outside the network, we received the login screen. After we punched in the username and pw, it kept saying incorrect. I suspect there is an authentication port that needs to be opened on our firewall but I have no idea what it could be. Pls advise, thanks. Share this post Link to post Share on other sites
anishjain 0 Posted December 30, 2013 I think you can disable the firewall temporarily, after that you can simply check using any port checker tool which you could help you understand which port the DVR system is using. Share this post Link to post Share on other sites
sohocctv 0 Posted December 30, 2013 This is a business network and firewall. I'm not going to disable the firewall, even if it is temporary. Share this post Link to post Share on other sites
