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?
Thanks
James
