Hi All,

I am trying to do port forwarding for someone so that they can view their cameras through a mobile app and over the net.

He has a Netgear Router (192.168.0.1) acting as the DSL modem and a Cisco router acting as the router (192.168.1.1). The Cisco seems to give the DHCP to devices on the network and places them in the 1.0 range. His NVR/DVR has an IP which resides on the 1.0 range as per the other devices (192.168.1.121).

In the Cisco router i have forwarded the necessary port (5000) to the IP of 192.168.1.121 but still cant gain access to the cameras over the web. I am almost certain this is because the port is not forwarded to that IP on the modem (Netgear). When i try forward the port to the DVR IP, it tells me it cant because i am trying to port forward to a different range. (Netgear = 192.168.0.1 ; DVR = 192.168.1.121)

How do i get around this? Can i add a route into the Netgear to the 1.0 range?

Can i perhaps tell the Netgear to not give out DHCP and leave that for the Cisco to do and then change the IP on the Netgear to 192.168.1.2?

Any assistance would be greatly appreciated.
 
On which device does the public IP sit, the Netgear or the Cisco? It doesn't sound like the Netgear is in bridge mode.

Have you tried forwarding port 5000 on the Netgear to the Cisco's 192.168.0.x IP?
 
The Cisco router should have two IP. One for the incoming or WAN (from the netgear. let's say 192.168.0.2) and another one for the LAN (probably 192.168.1.1 as is acting as DHCP).

So, on the netgear, you have to forward the port to 192.168.0.2 (Cisco router) not the DVR. And then on the Cisco, forward the port again to the camera or DVR (192.168.1.121).

If you want to make it simple, just remove the cisco and keep the netgear as primary DHCP for the network, but I don't know your environment, so maybe the cisco is acting as a more powerful firewall with more funcions or maybe a dual wan, etc.
