Unable to receive images from a remote video surveillance system in my browser and smartphone
Hello,
this is my first post in this forum, nice to be here.
I have a customer that installed a Geovision video surveillance system in their farm. The system was assigned a private ip address and of course using a pc in the LAN i can view live camera images connecting via http to the vdr.
The customer wants to be able to receive images using web browser or smartphones remotely.
The LAN is behind a Zywall 5 and I have configured port forwarding and firewall rule to enable port required to be open such as reported in the user guide.
When I try to connect remotely from the browser or using a smartphone I can see in the
firewall log that the connection is accepted and forwarded to the IP of the dvr but the remote browser cannot load the page (the connection was cancelled while loading the page) and the smartphone gives a connection failed error.
Ports required to be open are 80, 8866, 5511, 4550, 5550 .
I am facing with this trouble since a couple of days and cannot figure out how to fix it.
I remember that when I have connected from a pc on the lan some activex were installed in the browser and maybe this could be the problem for the remote browser.
I have downloaded the client application for iPhone and the configuration was simple but I receive a connection failed error also if I can see in the firewall logs connection entering and accepted.
Has someone already faced this problem? Any help appreciated.
Thank you
Nicola

Did you set those ports as TCP only? Live streaming services (such as video in this case) will usually require some UDP ports.

Thank you all for you suggestions. I have ask the customer to verify with the dvr technician if has been set the default gateway in IP configuration.
It will take a couple of days.
It was obvious to me that the IP configuration of DVR was fine, but actually I think it is not.
I will be back as soon as I have news.

Hardware Firewalls
Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
