my account was blocked last week and today got deleted for excessive updating (which is abuse according to DynDns) I don't know why is this happening and how can i stop it from keeping to happen. any ideas?

I have the DNS 323 sidebar gadget installed. is it related or is it from the DNS 323 itself?

I must mention that the DDNS on my router (Dir 655) is already used for my IP cam. I can't add the DNS 323 with the cam in the same time, or can i?

Please help

You should only have one DDNS service active on your network.  The purpose of this service is to periodically send your dynamically assigned IP address to dyndns so they can properly forward traffic between their static address/your selected domain name and your dynamic address.

I think the most logical place to put the DDNS service is in your main router that is always on and at the core of your network.  So I don't ever use the DDNS service in the NAS.  I guess its nice of D-Link to include one there in case someone has a really old router that lacks this feature.  But I'd suggest you turn it off on all devices except your router.

Why should i only have one DDNS service if DynDns allow up to 4?? and how can i use that with my existing IP Cam that i don't want to disconnect?

You don't get any extra benefit from having multiple devices on your home network with the DDNS service enabled.  You just need one to go out and periodically update dyndns.  And I don't really see why you would want to use more than one external ddns server in addition to dyndns.org.  Dyndns lets you define multiple domain names so you don't need to subscribe to multiple servers to get multiple domain names.

Maybe you are confusing DDNS with DHCP?  One device on your network also needs to be the DHCP server to give out dynamic IP addresses to each local device that isn't configured to use a static IP address.

The difference is that DDNS sets up a server somewhere outside your network that has a fixed IP address and domain name server (such as dyndns) with your local networks gateway that probably has a dynamic IP address and no domain name server.

While DHCP assigns dynamic local network IP addresses to all your internal devices.

I have my main router configured to provide the DHCP and DDNS service for my network and all other devices have those features disabled.  Note that some devices will use the term "Enable DHCP" or something like that to mean that they are receiving their local IP address dynamically rather than manually assigning a static address, but this setting is to be a DHCP client rather than a DHCP server.  Its okay to have many or all devices on your network setup to be DHCP clients but pick one to be the DHCP server.

ok here is more details about the situation;

first of all i am very new to the DDNS thing . I have IP Cam that i got few months ago before i buy the DNS 323, and i registered its DDNS with D- link but it only allow one name, and i am using the Routers setup for DDNS in this regard and everything works great for the IP cam.

now to access my DNS 323 remotely, i had to register another name for my DNS 323, so this time i registered it with Dyndns.org as i can't register more with D-Link. now how can i get this to work. isn't the new name for my DNS 323 (xxxxx.selfip.com) should be enabled somehow on the network, so if my IP cam is using the only spot for this on my router (Tools/DDNS) where can i enable the (xxxxx.selfip.com)

Hi joe_ottawa,
You have 1 external IP address. That IP is dynamic, so you want to bind it to a domain name and get it updated automatically when IP changes.

All you need is 1 device in your home network to send that update to your dynamic DNS provider. Either your router, or DNS-323. Not both of them.

As MountainMan already explained, use your router and disable that feature on DNS-323.

thanks for all your help guys. I think i just figured it out, thanks very much. I thought i needed two different host names to access my IP camera and the DNS 323, but i just find out that one address works for both and i think it is my router that redirect the incoming request accordingly.

That's correct.  Your router needs to forward the correct ports to each device on the network.  Since your entire network of potentially many devices is represented by a single external IP address, ports are needed to differentiate which traffic goes to which internal device.  For example, my router is setup to forward port 21 to the DNS-323 because this is the standard FTP port and it handles FTP traffic on my network.  You should probably do the same.

I"m not sure what the standard ports are for those webcams but you should setup the router to forward those ports to the camera's internal IP address.

Note that when you do port forwarding from the router to internal devices that you should use static IP addresses for those devices so they never change.  Disable the DHCP client on these forwarded devices and manually give them an internal IP address with port forwarding setup to go to that address.  Otherwise a future reshuffling of dynamic IP addresses will cause your ports to be forwarded to the wrong devices.

Its possible that some of this setup might occur automatically on your network using a system called UPnP.  Industry has realized that expecting normal people who aren't computer gurus to setup the complicated networks that are increasingly common is unrealistic.  So UPnP is supposed to automate many of these features to configure firewalls, routers, etc. to properly forward the right ports.  But my experience has been that this technology only works about 50% of the time at this point.  So its still important to understand how it works and check to make sure everything is right.

Best of luck to you.

thanks MountainMan;

This is what i have already. I reserved IP addresses to my devices on my router. when i use my host address (xxxx.dlinkddns.com) in the internet browser i get the IP camera login page. And when i use it with Filezella and port 21, i get my DNS 323 files. that was easier than i thought.

thanks again for all the help
