I read that you need to setup NAT loopback on the router. This allows you to connect to the WAN interface IP while you're on the LAN. Could this be the issue because we are using same ISP? Regards, K.Nizam

Keep forwarding 18004, and put rtsp back to 554. Changed tsp back to 554 and 18004 forward is still in place. No luck still. Regards, K.Nizam

I have another setup of DVR at home and that is using ISP B. And when I use my ISP A on iPhone I can view my home cams fine. So the problem is not about any particular ISP or blocking issue, the root cause is that the DVR and Remote viewing of cams cannot use same ISP. I would like to know why its like that and how can I fix it. Regards, K.Nizam

I setup port forwarding for 18004 and also changed RTSP port from 554 to 5554. The problem is still there. Regards, K.Nizam

Here are some details that can help you understand. I just have one router at my office which has DHCP enabled. I allotted 192.168.1.100 as a static IP to my DVR. I have enabled Free DDNS Service provided by CPPLUS DVR brand so my DDNS is xyz.cpplusddns.com I have setup port forwarding in my router for port 25001 and 80, I have iDMSS Lite installed on my iPhone which is setup to use port 25001 for remote viewing the cams. Everything works fine when I am at office over LAN i.e when I am connected to same office network I can view the cams on my iPhone and also on my MacBook. Everything also works fine when I am out of office at my friends place or at any public hot spots I can view the cams on my iPhone and also on my MacBook. The problem is only when I try to use same ISP network from remote location to view the cams. If the ISP which my DVR is using and the ISP which is used to view the cams are same I cannot view the cams. For example: DVR Using: ISP A iPhone Using: ISP B =Everything works fine! DVR Using: ISP A iPhone Using: ISP A =Nothing works Regards, K.Nizam

I am using iPhone but have also tested on Android the results are same on both. Where do I change the RTSP port? Are you sure its something to do with ports? I was thinking about nat loopback issue. Because I can view the cams without problem using a different ISP. Regards, K.Nizam

Hi, I am having a strange issue when remote viewing our cams using same ISP which my DVR is using. In my case I have 2 ISP's "ISP A" & "ISP B" My DVR is setup with proper DDNS and port forwarding using "ISP A", this is working fine for viewing the cams on LAN and also remotely using "ISP B". I can access my cams using browser and also through iPhone App's without ay problem. Here the problem is, my cellphone 3G ISP is same as the ISP I am using for my DVR i.e "ISP A", when I try to view the cams it does not connect. To make it simple as soon as i leave my office and start using my mobile 3G network which is same ISP as my DVR I cannot view the cams but when I try to view it from my friends cell phone which is a different ISP I can view the cams without any issue. Can anyone help here to fix this issue? Regards, K.Nizam
