Hello! I'm new to this forum. Have been trying to resolve this issue for my mum for the last week with no avail so I'm turning to the experienced tech experts here for help... in desperation.
So here's the deal, I'm trying to gain access for remote viewing of CCTV (NVR) which is made by Dahua. The modem/router is Huawei hg532d - which is both wired and wireless.
The NVR's network settings are as follows:
static ip address which is 192.168.0.108 (DHCP is not selected as doing so turns everything into 0s)
Subnet mask 255.255.255.0
Gateway 192.168.0.1
TCP Port 37777
UDP Port 37778
HTTP Port 80
RTSP Port 554
The IPv4 address of the computer that is attached via ethernet to the modem is 192.168.0.2
Subnet mask 255.255.255.0
Default gateway 192.168.0.1
(Now this modem/router's original factory setting IPv4 address would be something like 192.168.1.x, and the gateway would be 192.168.1.1 - but because it wasn't the same as the NVR's I changed the modem's one without changing the NVR's since I couldn't change it on the NVR system for some reason)
According to guides I've read, I have the following set up on the port mapping section of the router:
Protocol: TCP/UDP
External Start Port: 80
External End Port: 80
Internal Host: 192.168.0.108
Internal Port: 80
Protocol: TCP/UDP
External Start Port: 37777
External End Port: 37777
Internal Host: 192.168.0.108
Internal Port: 37777
Protocol: TCP/UDP
External Start Port: 37778
External End Port: 37778
Internal Host: 192.168.0.108
Internal Port: 37778
I would have thought by doing this the ports would open and everything would be fine but no. When I go to canyouseeme I get "connection time out" on all of the above ports, viewed with the external IP address of course.
I've turned off the firewall in the router. I don't have other firewalls or antiviral software running either.
I've contacted my ISP who have informed me they are not blocking any ports. I've also called the huawei modem company without much luck either.
Now prior to changing my ISP and modem the remote viewing worked fine, so I'm pretty sure it's a problem with the configuration within the modem/router. And I don't know whether this "bridging" thing needs to be done since it's a modem and a router. I haven't changed any of the original settings on the NVR (because I can't, and I don't know why - that's another issue in itself).
The program I am trying to remotely view the NVR has an external IP address 123.2.36.62. I don't know whether this particular address needs to be filled into the port settings or not. It seemed that this address was needed in the old modem settings which I don't have access to now (it was also not set up by me). Is there also something about inbound DMZ setting?
Funnily enough, although the NVR is directly connected via ethernet to the modem/router when I used cmd -> PING 192.168.0.108 (this is the NVR ip address) I keep getting:
Reply From < my computer's IP address i.e. not the one I pinged >: Destination Host Unreachable
So honestly I'm getting quite confused about all of these issues and I'm really not sure where the problem may be. If anyone can help me it would be greatly appreciated. :bow:
