Post subject: Remote Viewing - Clover DVR behind router using DSL modem
|
Basics:
Its a clover usa DVR system that is supposed to allow remote viewing over port 5800. I'm able to get it working just fine within my network (LAN) but not from outside the network (WAN). I've assigned a static IP to the DVR (outside of the default DHCP range) and port forwarded all neccesary ports (300 & 500). That wasn't working, so I instead set that IP address to use DMZ. I've verified my settings with DYNDNS, and i've checked and rechecked all of my network settings, but I still cannot connect remotely.
Does anyone have any clues? The manual for the system didn't provide much troubleshooting information. I'm desperate at this point...

I've also changed the port to 200 to see if my DSL modem was perhaps blocking 5800.. Port 200 works for LAN, but i'm not able to access it from outside the network.
Also.. I've been testing this by using my external IP : port number. That external IP is what my DSL modem is getting.. that's what I should be using, correct?

You should try your remote access from somewhere other then the same DSL circuit. I say this only because others have had similar issues as you are having only to find it works fine from the outside but they can't use the public IP from within their own LAN.
I can access my public IP from within the same LAN but others say they can't. Something worth trying before you drive yourself nuts changing a bunch of settings that will never make it work.
And yes, sounds like you are doing it right.

Agreed, you must actually be using another internet connection for testing. I would leave it on DMZ only until you get it working, then step back. One other test is to enable remote admin in your router and use that to test the DDNS function. Also, you are using the DDNS in your router, not the DVR, correct?

I'm actually not using dyndns right now. I figured i'd just use the ip address and port. Once i can get the remote features to work, ill setup the ddns. Should I be using it? as far as I know, all that really does is assign a hostname to my ip, and is mostly for convenience factor (helpful with changing IPs).
So in summary, I've tried this now from outside the network. I flashed my router with the latest firmware, set it back to factory defaults and started over. I setup my port forwarding. I also assigned the DVR a static IP address outside of my dhcp range (I'm assuming there should be no issues there). So im forwarding only port 5800 to that static IP (should I be forwarding any others?).

I know nothing about the clover DVR but no doubt the instructions will tell you which ports need to be directed from the WAN to the DVR LAN IP, and if those are TCP and/or UDP.
The purpose of assigning the DVR's LAN IP to "DMZ" instead is to temporarily (or permanently) avoid the need to figure all that out. If it doesn't work on DMZ it not going to work with port forwarding.
Your client, whether it is proprietary or IE should work exactly the same remotely as it did locally, with only the target IP changed.

The documentation referred to using port 5800, which I have setup in port forwarding. My setup is as follows:
DVR connected to linksys 54g router. router connected to DSL box with XXX.XXX.XXX.XXX IP. I've assigned the DVR a static IP outside of the range of my DHCP so the internal IP doesn't change and cause problems for port forwarding. I've forwarded port 5800 to the static IP for both UDP & TCP (although the documentation says just to forward TCP, I've tried it both ways). Registered with dyndns, and setup a domain to forward to my Sprint assigned IP. While testing, I've avoided using the hostname forwarding, and just been trying h++p : / / IP . ADDRESS : 5800 . When on my LAN, this will launch an active x control and install an app to allow remote viewing.
Currently, I cannot connect from outside the network. I can ping my IP successfully, and I've even tried using telnet to access the client (which I can do internally), but to no avail.
The computer I'm using to attempt a connection is located behind a router, with windows firewall turned off. I've tried opening my ports on this side as well, but no luck so far.
I can provide any additional info about my config if anyone needs it to diagnose.
thanks!

What's the DSL modem model? Is it acting as a NAT router? In other words does the Linksys see the actual internet IP on the WAN port or is it seeing a local DHCP-supplied address from the modem?
Where are you finding the internet IP that you are using for remote testing?
Again, setting the router admin login to allow remote access from any internet IP is a good way to test this stuff without initially involving the DVR. And, again, if you assign the DVR to DMZ you can take out the variable of port forwarding.
I think either your modem is also a router (and blocking ports,) or you are using the wrong internet IP when trying to access it remotely. There isn't anything left!

I found my IP address by both using google ("my ip address" or something similar came up with it). And I also used the IP address found with the auto find feature on dyndns . org . I have the Login & PW for the DSL modem, you're saying I need to check to see if NAT translation is available, and look for possible alternative IP addresses? I wouldn't be surprised if DSL was the cause of this whole mess.. I'm now working remotely so I'll have to talk my dad through the process of checking...
Thanks for the input!

I too am encountering the same issues. I am using cable and like yourself can access everything "internally" but can not externally. VERY frustrating. I have everything set as per "tech support" recommendations (yes I called them) which is STATIC IP, port 5800, using my "public IP" for external access, did all the remote forwarding for the rourter (even bought a new wireless router and modem for others reason than just this) with no luck. The product claim was "connect via the internet" and "remote connect anywhere in the world". All of those details were main reasons for buying this product. My bad. I suppose now I should have searched for existing issues from other users/forums.

By the way....my partial solution around this issue (for now) is to connect to my home computer via remote connect from my laptop and accessing my dvr/cameras that way. But that only offers a small consolation as I can't remote connect from work (restricted).

I have a Clover Model CDR-4170 - Probably lower quality than your model, but I lifted the following out of the User's Manual:
NOTE:
- Router has to be set as a virtual server (or port forwarding) in order to utilize the DDNS service (See section 5.11 for more details).
- Do not use the public port numbers.
- Four Port numbers (in sequence) including the default port number should be forwarded.
- Ex: Default port number: 5700.
Forwarding ports: 5700 / 5701 / 5702 / 5703.
Maybe you need to forward 5800-5803 ??
Also in my LinkSys router it says that while Single Port Forwarding is Enabled, then DMZ takes a back seat in order of priority.

In my LinkSys Router, I ENABLED "PORT RANGE FORWARDING" that I named CLOVER - Starting Port 5700 - Ending Port 5703 - Protocol BOTH - IP Address (Address of the CLOVER in my LAN) - Checked the ENABLE Button.
I am able to view and administer the CLOVER using my outside (WAN) I.P. Address and my inside (LAN) I.P. Address. I haven't tried to access it from another computer yet - I'll try that tomorrow when I have access to another computer at work. But I'm pretty sure that I'm accessing it from outside the LAN.
One other thing that seems quirky - When I type in the I.P. Address in Clover's Remote Viewer, I think it is necessary to fill in all the numbers with leading zeros.
For Example:
Instead of - 22.85.221.44
It is - 022.085.221.044

minko....thanks so much for that bit of information. Reading it all certainly makes some sense. I am going to try all of this (one at a time to determine what works/fixes the issue) when I get home tonight. I appreciate your time and information. BTW my model is the CDR-4570 but I don't know that it would make a difference. I'll keep you posted and thanks again.
