    Ok so I work for a party store and I have setup his security cameras to be viewed online. So I opened the ports and it has been working for about 3 months but recently it stopped. So I checked the connections all the basic things and checked to see if the ports on my router were still open and they were but still nothing. So I decided to delete the ports and re-open them. It worked!.......for only about 2 days tho then they stopped working again. I don't know if is that they are closing or what because when i look on the router they are open, but they are not able to be viewed on Canyouseeme.org. and I am not able to access the domain I created. Can anyone please help. the owner of the company is going on vacation in 4 days and I need to get this system up and running again.
    thank you for any information or help

    Hi PartySS, and welcome to TSG.

    Does the Internet connection to the store have a static public IP address? If not, the address may be changing every so often?

    What do you mean by, "the domain I created"? Are you using some Dynamic DNS service?

    yes i made a dns thru the camera company we purchased from Q-See. And I'm not too sure if we have static or dynamic im pretty sure its dynamic. I would have to call the cable company to find out. But if it is dynamic what could i do to solve my problem. Sorry for the noob questions I'm not too comp savvy.

    If the camera controller at the store has dynamic DNS support set up to use the camera company's dynamic DNS service, you should be all set to handle a changing dynamic public address from your ISP.

    Is the camera controller set up with a static private IP address on the store's LAN? Port forwarding would not work correctly if it has a random DHCP address assigned to it.

    When you are checking for a working connection, are you doing it while you are on the LAN at the store? Some routers have problems trying to handle connections to their public address from an internal LAN IP address. This is usually an It Always Works or It Never Works condition. This is a wild guess, but maybe your router is getting lost every so often. Having you web browser of camera software going through a free public proxy server would be one way to check if this is the problem.

    ok like i said before I'm not that great with computers but I'll try and explain it the best way I can. I pretty much just connected the DVR with an ethernet cord that went into a huge ethernet switch that is feeding from the router. It auto assigned an IP to the dvr and when i opened everything i set it to that IP. I also set up to view the DVR from a DNS that the company provided everything there is fine it says active and such. Recently the owner started to redo a few things and he got a new ISP and switch a few things out I Pretty much Re did everything I did from the start to remake another and like i said it worked for a while and then it all of sudden stopped. It would work again for a few days after I messed with the Port Forwarding and it would work for a few days then stop again. and now it won't work what so ever.

    From what i can see in the router settings for LAN it is setup for a DHCP server and has a ranged of IP.

    The camera controller needs a static IP address on the LAN. Otherwise, port forwarding is working with a moving target. You need to give it an address outside of the DHCP range of the DHCP server, but within the sub-net range of the router. If the DHCP server supports it, you can also use MAC address reservation that always assigns a given LAN IP address to the MAC address of the controller.

    The router gives me an option to reserve the ip that was assigned to the dvr and it says that it will keep it the same. I did that and now when i go to canyouseeme.org it says the connection is refused

    Because it was not a static it changed the dvr IP so I just reopened the port with the new ip and put it as a static IP for the dvr and now its working, Hopefully it stays working. Thank you for your help. I really appreciate it. If it doesn't work I know where to come. Thanks again so much.
