JamesG60 0 Posted March 26, 2015 Hi, I'm new here. I've delt with multiple enterprise/server driven networks before but never with CCTV or server 2011 so I hope someone here can help with an issue I'm experiencing. It's also been a few years since I've delt with networks in general due to a career change so I may be a bit rusty. Anyway, on to the problem at hand... I'm trying ot sort out my mates CCTV at one of his yards. This system is comprised of the following: 24 cameras (most fixed, some on a tour) 2 QVIS 16 channel DVRs Windows Small Business Server 2011 NetGear 16 port switch DrayTek 2830 Wireless router/ADSL Modem 3 Workstations A handfull of iOS devices DVR 1 has the following network settings: IP Address: 192.168.1.101 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.254 TCP Port: 9221 UDP Port: 37778 HTTP Port: 80 RTSP Port: 554 Max Connections: 20 Prefered DNS 8.8.8.8 Alternative DNS 8.8.4.4 DHCP Disabled Transfer Mode Disabled LAN Download Disabled IP Filter Disabled NTPServer:1440 Disabled DDNS Disabled DVR 2 has the following network settings: IP Address: 192.168.1.102 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.254 TCP Port: 9222 UDP Port: 37778 HTTP Port: 80 RTSP Port: 554 Max Connections: 20 Prefered DNS 8.8.8.8 Alternative DNS 8.8.4.4 DHCP Disabled Transfer Mode Disabled LAN Download Disabled IP Filter Disabled NTPServer:1440 Disabled DDNS Disabled In the DrayTek Router preferences under NAT>Open Ports I have the following DVR 1 TCP Incoming Port: 9221 Outgoing Port: 9221 Internal IP: 192.168.1.101 External IP: Can't remember but ends with .235 DVR 2 TCP Incoming Port: 9222 Outgoing Port: 9222 Internal IP: 192.168.1.102 External IP: Can't remember but ends with .235 Both DVRs are on WAN1 (only one active) I can view both systems over LAN perfectly but can only view DVR 1 via WAN. I can't find anything related to DVR1, either ip or port, in Windows Firewall, DNS, DHCP on the server that would be allowing 1 to work and not 2. I have set up a 3rd DVR (DVR3) on a 1m ethernet next to the switch and manually copied across the settings from DVR2. I then unplugged DVR2 from the switch and replaced it with DVR3. This is also not viewable over WAN. This leads me to believe it is a port forwarding issue rather than signal loss/noise (rather long cat5 run). This is supported by the fact that DVR2/3 are viewable over LAN. Is there anything I'm missing or anything anyone can think of that would be getting in the way of port 9222?

jazzar 0 Posted March 26, 2015 any firewalls maybe blocking traffic ? try running an open port checker to see if the 9222 and 37778 ports are open. try swapping the port settings around for dvr1 and 2 and see if 9221 is reached on the other DVR. Last suggestion run wireshark and see if you can capture and analyse where its going wrong. Share this post Link to post Share on other sites
Numb-nuts 1 Posted March 28, 2015 If you have 2 DVRs on a single network range, before port forwarding the Draytek you should reserve the IP address of BOTH DVRs I also notice you have the same RTSP port on both devices. One port serves one device only. It's like two fat ladies trying to get through the same doorway only onewill succeed Share this post Link to post Share on other sites
Samir 0 Posted March 28, 2015 try swapping the port settings around for dvr1 and 2 and see if 9221 is reached on the other DVR.I'd try this first and see what your results are. If only one works, it's definitely a routing issue.If you have 2 DVRs on a single network range, before port forwarding the Draytek you should reserve the IP address of BOTH DVRsI also notice you have the same RTSP port on both devices. One port serves one device only. It's like two fat ladies trying to get through the same doorway only onewill succeed This is going to be important too. You'll need to change the ports on at least one of them. In fact, now that I'm looking at it, looks like you have the same udp port for both. Try changing that as well.
