FurryNutz. I don't know how to post images in here. So an example of the PF rule I was trying to use is here: http://mytechco.com/dir-655/

For future reference:  Adding Screenshots In A Post

Ok so I brought out my Rev C and connected it to my Laptop using Windows 7x32.
The router had a factory reset on it as soon as I went to the web page at 192.168.0.1 using IE11, I got the set up wizard. I cancelled it and input the PF configuration seen on your linked page. I used my laptops IP address of 192.168.0.100 instead since it's the only device LAN wired connected. I selected the check mark to enable it then selected Save. I didn't see the error message you reported. I saw the reboot now or later buttons. I selected the reboot now and the router rebooted. This is not to say that you don't have a problem. I would have to put this router online as the main router and test again. From offline review and configuration, i'm not seen the error message though.

Is that with Firmware Version 3.02 ?

[FurryNutz]

Yes.

Just curious here, how many devices are all connected to this router at this one location? Total wired and wireless?

[CaseyJanke]

About 6 ip phones
About 6 computers
1 server
24 ip cameras

[FurryNutz]

These cameras wired or wireless?

[CaseyJanke]

Everything I mentioned is wired. Only wireless would be peoples cell phones and such. Cameras go to a POE switch. Computers go to a regular switch. and the phones go to another switch (but probably don't have to, I just isolated them as they were having voice quality problems). The VOIP quality problem was the bandwidth. The VOIP call transfer problem was the (or I hope) RV series routers.

[FurryNutz]

All this on a home class router. Hmm. I'm wondering if maybe that the device connection count on this particular router is maybe having bandwidth and configuration issues due to all whats connected. This router isn't really meant for high capacity connections. Maybe 30 at most.

I would try this, if you can get onsite. Use the one PC there that's wired and disconnect ALL other devices. Power them off or disconnect them from the router. Do a factory reset and set up an IP address reservation for the PC and 1 camera. Then go in and configure 1 PF rule. See if the setting will save. If so, reboot now. Disable uPnP as well and reboot. If still working at this point, connect the rest of the cameras and see.

I believe there is a limit on configuring and adding rules. It maybe 24. I don't know why D-Link does this so don't ask. Remember, this is a home class router, not a business class router.

If these cameras don't need much router management aside from PF rules, you might try using Static IP addresses ON the cameras instead of setting up IP reservations on the router as this will help save on reservation limits as well. Ya, there's a limit on reservations you can use on the router. So using Static IPs on Cameras, Printers and devices that don't need much router management is highly recommended.

[CaseyJanke]

I am definitely not a network expert, it is probably my lightest skillset in the IT area. Given that though here are my thoughts:

1. The ip cameras all have static ip addresses, as do all the printers and the server.

2. Although many businesses now days use some kind of cloud business app, making outside communications critical. This client has all their main apps behind the router. So for the most part, other than email traffic, internet browsing and phone, there isn't much coming in or out of the network. The cameras talk to the camera server, so most communications should be within the switch. Their main apps are Quickbooks and a scheduling app. Both reside on the server, along with their files, so again, most communications should be done through the switches, not much going in or out of the LAN.

So my understanding (albeit it basic) tells me that most communications are done through the switches, not the router.

[CaseyJanke]

Also, the cameras themselves don't need any PF rules. The only PF rule is port 81 so the owner can view the cameras from his home computer and iPhone. That definitely uses the router, but it isn't used often. So I only need 1 PF rule and about 5 QOS rules (for the phone). Other than that not much really going on at the router.

[CaseyJanke]

And if I could have gotten the DSR-500n to connect to the internet I would be using that. I called tech support on that and they had me clone my pc mac to the DSR-500n, but it still wouldn't connect that way either. So after 2 hours I gave up. I don't need wonky.

[FurryNutz]

Are the static IP addresses set out side of the routers default IP address pool? 192.168.0.100 thru .200? Static addresses should be outside the pool, not with in.

Ya, switches are good.

Is the PF rule for a camera IP address?

[FurryNutz]

Connecting the DSR to the 6141 modem?

Did you swap LAN cabling between them?
Did you try the DSR at a different location like home?

And if I could have gotten the DSR-500n to connect to the internet I would be using that. I called tech support on that and they had me clone my pc mac to the DSR-500n, but it still wouldn't connect that way either. So after 2 hours I gave up. I don't need wonky.

[FurryNutz]

For now, I would get onsite and start with 1 camera and one PC and see if you can get the router to accept 1 PF rule. Disable uPnP. Do this while ALL other devices are disconnected from the router. If you can get one going, then configure the rest of the router for what you need then if all goes well, connect ALL devices.

Let us know how it goes.
