Assigned Vs. Static Ip

[tigerbeer]

Hi everyone,

Phew! spend the whole day configuring the CCTV box so that I can see whats going on in the shop while I am at home or anywhere.

we were asked to get a specific router modem which is Zyxel 650H. Got that and hooked up with Max-Net. Did a set up on the dvr box to Static IP and 192.168.x.x

then used the services of dyndns.com for a free account of host services and set up whatever IP address the internet connection is with MaxNet.

So everything works fine. I can see whats going on in the shop while being on the internet.

BUT. when the router is re-started, a different IP address is assigned for WAN. So I have to go back to dyndns.com to write in the new assigned WAN IP address. Thats not going to work cause anyone can pull out the plug on the router and i wont be able to monitor anymore unless i know what the new IP is in the shop.

So i try the router software and try to assign a static IP based on whatever the last WAN IP is. I restart the router and no ADSL. well cause the router can't connect at that static IP.

So what do I need to know is whether Max-Net can assign me a static IP that does not change? Is it possible? I do not really wanna waste a long time waiting on the phone and the language can be a barrier when it comes to speaking technical stuff.

The DVR machine does give me an option of using DHCP or PPPoE. Both of which I think still need a static IP or am I missing something there? The only option that worked for me whole day today was the STATIC route.

any information or advice from some of you professionals would be appreciated.

May you change the service to http://www.no-ip.com

Sign up for a new free account. Download the DUC Client for your OS and install it on your server. After set evrything incl. the required port forwarding, everything should run without problems.

Keep the following in mind:

1. you can NOT setup an static IP in your Router, this is done by the ISP and they change if you don't have the service for static IP;

2. you need to use one computer 24/7 as server where the DUC is running to give the IP-info to the DNS Service provider like no-ip.com because this computer submitt the IP every let say 20 min. (depend on the settings you choose) to the DNS Provider and if you connect you use an Domain Name and not an IP.

Any more question please post here.

Cheers.

Some routers automatically update DynDNS with the new IP. I know my D-Link has that feature. Maybe you should look into getting a new router if you don't want to worry about having a dedicated box connected to the internet.

If you're using DynDNS settings in your router, then you should be pointing your browser, etc. to the DynDNS name -- NOT the IP address.

For instance, let's say your DynDNS name is [email protected] then it doesn't matter what the IP you're assigned because via your subscription to DynDNS and the router settings it will resolve that IP address to [email protected]. Hence, always point your browser or webcam application to [email protected] (not the IP address) and you won't have to do anything. If the router re-boots, it will resolve the new IP to [email protected] automatically.

Reimar,

Thanks for replying. The thing is that there would not be a computer there next to the device. So this option cannot be used. I shall have a look at the site mentioned though just to keep in mind. thanks.

Norrad, yes the modem has this option and only realised using it after you mentioned it. I have not gone back to the shop as yet and will try it out first thing tomorrow. It should work.

Rice King, thanks. I will do it first thing tomorrow morning. I had not gone to the part of using DynDNS settings yet.

Cheers all and thanks for the help.

I am not sure where or how the DVR is in your setup ( is it just on yuor wired network ) , so I will give my advice on just your IP camera and router.

first your dyndns address - you will need to enter your login or email and password for the dyndns service - in the router setup pages you will find a dyndns setting which will probably have a few of the providers of dynamic DNS resolving services listed in a dropdown menu - the most popular seems to be dyndns.org , but you could check out the others and see what works best for you. The job they do is update the IP address for your router that is assigned by your ISP and associate it to your dynamic dns login - ie. tigerbeer.dyndns.org will have the IP address that your ISP provides you for 24 hours stints if you have configured your router to login to dnydns and update it regularly.

onto your IP cam. I am assuming you login to the IP cam via you webbrowser which means your IP cam is running a http webserver and serving that information to the webbrowser that you are using ( these at the moment seem to require an activeX applet for Iexplorer or a java applet for firefox - some browsers on mobile phones will also work )

you should setup your webcam with a static IP address as this will save confusion , so give it a static IP of 192.168.1.20 , subnet mask 255.255.255.0 and gateway of 192.168.1.1 ( this is assuming your network is numbered 192.168.1.x and 1.1 is the router connected to the internet - if not adjust as suited ) also you need to set the port that the IP cams weserver servers its pages from. It will probably be set at port 80 which is the defaul port for http webservers but some ISPs will block incoming requests to port 80 as they don't want people to run webservers on their home connections - if this is the case you need to choose another port - suggest 4480 or 8080 and then when you request the page you will have to specify the port as it is not the default http port any more , will explain this a little more later.

now this will allow you to look at the IP cam from inside your network , now you need to enable connecting to it from the internet. To get to your router from the internet you will put this in your browser http://tigerbeer.dyndns.org/ and that will send the request to port 80 on your router - you then need to port forward that request to the static IP you have assigned the IPcam - portforward.com has good instructions for most routers . You will instruct your router to take any requests on port 80 and give them to port 80 of the IPcam ( these port numbers can be anything from 0-65535 just make sure things line up ). if you want/need to use another port number you need to do it in the port forwarding - keep in mind you could port forward 4480 from the internet side of your router to port 80 on the IP cam and that will work , you will just have to put http://tigerbeer.dyndns.org:4480 in your browser so you are asking at the correct port and it will be forwarded to the Ip cam webserver.

hopefully that is not all too confusing - I have tried to go into a bit of detail to maybe also help others.

post any more questions and I will try and help

stumonster, thank you for your help. I do not however have IP cams. They are all wired cams. I do however intend to install IP cams at home so this write up would come up handy for me. thank you very much.

I would be setting up the router in a little while to do the auto update to dyndns for me though. that is what i was looking help on when i started this thread.

TB..

If you like to use IP-Cameras, which is a good solution, you have to keep something in mind;

First at all is that you need for each camera 2 ports to be enabled in the router. That means that as more cameras you use you have to double that amount to get the amount of needed ports.

Second from my own experiences, there is only one low cost Modem/Router available on the local market to handle more than 4 cameras continue connected 24/7 and get the best pictures. That Modem/Router is from Level One the WBR 3460 A or B which is an ADSL 2/2+ router wireless, 4 port and the cost is below 2,000 Baht. The big advantage of this router is that you have up to 1024 Ports available for forwarding and an 100% Camera support. Most of the Mode/Router having 16 available ports or even just 8!

Setup of the Level one is a bit different from others but easy as well. I use that Modem/Router by one customer with 69 cameras ( IP and Wireless) connected without any problems.

You must also keep in mind that the Modem/Router must have an Web Administration Interface, which means that you must be able to remotly connect from anywhere to administer that Modem/Router. With the Level One you can do that.

Cheers.

Reimar , I am unsure as to why you say 2 ports are required - surely if you just want to monitor/use the camera via its internal webserver only 1 port is required per camera.

Second from my own experiences, there is only one low cost Modem/Router available on the local market to handle more than 4 cameras continue connected 24/7 and get the best pictures.

have you tried the WRT54GL with tomato firmware ? - though it only has a RJ45 port for WAN connection.

[tigerbeer]

thanks everyone for your help. I got it sorted out. The only thing I needed to do was to fill in the blanks for Dynamic DNS settings in the router software. So it auto updates dyndns.com with the latest IP address for WAN. Works perfectly now. FYI the router modem is Zyxel 660.

Make sure the cameras are placed out of easy reach and sight if possible.

I remember Maejo Man told us when his house was burgled, the culprits stole his security cameras too.
