Nevermind! I've resolved the issue by just swapping out my modem/router! I left the router connected. For those of you having trouble with a new modem/router, make sure you have UPNP enabled and port forward whatever ports you've indicated on your DVR, using the ip address assigned to your DVR. Don't try to port forward on the router attached to the modem/router! Just have the DVR connected to your modem/router! It's much more simple.

There was no specific option for DMZ on the modem/router. But I tried using the IP-passthrough option, and it did not work unfortunately. I have attached a picture of the advanced section. I have checked through everyone of them and there was no option for DMZ. I'm guessing this is because this is a very old modem/router. Any other options? I'm thinking of replacing the modem/router completely with a new modem and have the router attached to the new modem. But this time, I will plug in the ethernet of the DVR directly to the new modem that supports UPNP so that I can eliminate the port-forwarding/DMZ issues. Would this method be viable?

Thank you so much! That cleared up a lot of things! I'll let you know in about 11-12 hours if it worked! Thanks again!

Bump. Anyone?

So with the IP address of the router obtained, I should do either of those options that you've given me or both? Option A) "You need to port forward the IP address of the Tenda to your modem/router" I use the IP of the Tenda to port forward the 4520-4529 and 80-80 on the modem. But what about the port forwards on the router? Should I disable them? Option B) "add the IP address of Tenda to the DMZ" I just add it to the DMZ of the modem? Will I still have to do option A? And should I delete the existing port forwardings on the router that I have shown in the picture?

Hi, I do not have access to the first two at the moment. But the default gateway of the second one was 192.168.0.1. But I do know the IP address of the DVR: 192.168.0.101 (as given by the DHCP). Should the IP LAN address be located on the device itself? I won't have access to it until tomorrow morning. When I do obtain them, what should I do? Thanks.

Hey Phil, so I just first login to the the Tenda's router page and record its IP? Wouldn't that be the default gateway? If not, what do I record? And with the IP, I would have to port forward (the same ports on the router) on the modem's settings? If so, do I have to disable the port forwardings on the Tenda that's used to port forward the DVR? Or would be easier to use your latter method? Adding the IP of the Tenda to the DMZ of the Modem? And how would this affect the UPNP? The modem doesn't support it, which is the reason why I'm using the router. Thanks!

Hello, I am here because I need help with viewing my DVR through the Samung "IPOLIS Mobile" app and through the online Ipolis site. The site basically uses my public ip address with the port number associated with my DVR (e.g. xxx.xxx.xxx.xxx:80) I have AT&T as my ISP. I'll describe everything that I did. I'll start by describing how my modem/router is set up. The DSL jack is connected to my modem, which supports up to 4 ethernet slots. The modem is unfortunately an old model that does not support UPNP. Which is the reason why I went out and bought a separate router that does. For the modem, 3 of the 4 ethernet slots are filled for miscellaneous desktops. The last one is linked to the router (Tenda is the company). The jack was properly linked to the WAN port. And 4 other extra slots come with the router. The DVR is connected to the router, so that it gets the UPNP service. Now on the Tenda router's settings page, I have enabled UPNP manually. Everything is fine and left as default. (Notice: The internet set up works perfectly fine. I even turned on the wifi for the router, which works perfectly fine.) Now for my DVR, I have followed all directions clearly. I have set my IP type on the Network Connections's "Interface" tab to DHCP, which automatically obtains my ip for the device and etc. The DNS was left at manual (set by default). Now on the "Ports" Tab, I have left the protocol type to TCP, Device Port (4520-4524), HTTP Port (80), and secure video transmission (off) to its default state. After doing so, I clicked OK, which prompted with a SUCCESS notification. The next step according to directions was to go register my product on the samsung ipolis site. I clicked register, made my account, and registered my DVR with the proper model version (SDR-B3300). The purpose of the site was to set up the DDNS, which I properly did. Everything was successful. Now the directions take me back to the DVR. I opened up the DDNS section of Network Connections. It loaded a page where I select "IPOLIS" as the DDNS Site and write my DDNS address. (e.g. www.samsungipolis.com/name). And then I selected YES for Quick Connect. And then clicked OK. After doing so, it prompted me with a SUCCESS notification. Now, everything should be complete. The directions on samsung lead me to methods of remote monitoring my DVR. The online method requires me to go back to the samsung ipolis site and click on a video icon next to my DDNS server, which leads me to another link of my Public Address with the port number "80" (since the device was set to 80). But the page does not load. I have tried the same link on Chrome, Internet Explorer, Safari, and Firefox. All of them won't load. So I scratched this method and tried the mobile app. For the mobile app, it requires me to put in my DDNS address and the RTSP port (the last number of the device port range [mentioned above] which should be 4524), and the id/pass to my DVR device, which I put correctly. The live-view camera would not load. So now, I tried a method called port-forwarding on my router's settings page. I went to the port-forwarding section and added in the port ranges along with the IP address of the device manually. One was for the device port range (4520-4529) and another for the HTTP port (80-80). And I set the protocol to TCP (I even tried BOTH, which includes TCP and UDP). And I made sure that my device was recognized along with its mac address on the DHCP client list. And then I retried viewing the DVR online and the mobile app (changing the settings on the mobile app/online of course, according to the port ranges set on the router's page). Both methods would not work. I tried changing the device's HTTP port to 80, 81, 82... 89 (changing all the other settings of course) and refreshing all the other settings on the DVR device. I've also tried changing the device port range from 4520-4524 to 452x-452x (the last port number is automatically set so that it ranges to 4 numbers above (e.g. 4521-4525, 4522-4526, ... to 4525-4529). I have attached a picture of the port-forwarding page. I don't know if this is relevant but on the bottom it says that the Multibrowser supports from 4505-4530 and supports HTTP 80. I have tried calling Samsung, but the general technicians could not answer my question. They forwarded me to an expert technician, but they won't be available for another couple days. Unfortunately, I am desperately in need of a solution by tomorrow. Please. If anyone can help, that would be great! I honestly think that the problem lies with the port-forwarding options of the router. If I do call AT&T, what would I specifically ask them to help me with? I thought that setting up the port-forwarding was flawless and straightforward. Thank you for your attention!
