Port Forwarding using a Linksys Router - Configuring the DVR

Configuring the DVR to pick up an IP address
1. Right Click and select Main Menu 

2. Select  Setting

3. Select Network

4. Check the box next to DHCP and click Save

5.  Select Shutdown

 6.  Set to Restart system and click OK

 7. Right Click and select Main Menu (Now we are Identifying the IP address) Then Select Settings, Then Select Network.

 8. Uncheck the box next to DHCP, write down the IP Address, Subnet Mask, and Gateway, and click Save

To setup port forwarding on this router your computer needs to have a static ip address.
Or you can take alook at our Static IP Address guide to setup a static ip address. When you are finished setting up a static ip address, please come back to this page and enter the ip address you setup in the Static IP Address box below.

Open a web browser like Internet Explorer or Firefox. Enter the internal IP address of your router in the address bar of your browser.

In the picture above the address bar has http://www.google.com in it. Just replace all of that with the internal IP address of your router. By default the IP address should be set to 192.168.1.1. 

You should see a box prompting you for your username and password. Enter your username and password now. By default the username is admin, and the password is admin. Click the Ok button to log in to your router.

 

Click the Applications & Gaming link near the top of the page. 

You should now see a new menu. In this new menu, click Port Range Forwarding.

We will list a series of lines here that will show you exactly how to forward the ports you need to forward. Some DVR requires you to forward the following ports: 80,37777,37778. Go ahead and enter the settings shown above into the Port Range Forwarding menu. 

When you're finished, click Save Settings near the bottom of the screen to save your changes. 

 
And that's it! You're done!

How To Setup Two or More Routers Together

One of the most common issues people encounter is when they have more than one router hooked up. Sometimes people don't realize their modem is also a router (Such as DSL) and other times people hook up an extra router to use things their router/modem doesn't have, such as wireless.

So now with 2 or more routers hooked up people start to realize port forwarding & port triggering isn't working. This is because they are only setting up the port forwarding or triggering in one router, which is what they should be doing! Now let me explain, no one wants to setup port forwarding & triggering rules in two or more routers, they should only need to do it in one, making things simple. But you may ask "If I have more than one router how can I keep it simple?" The answer: DMZ

First off DMZ is supported by nearly every router/modem out there. What DMZ does is allow you to tell the router to forward all incoming connections to a single IP address. So in this case we will setup DMZ in the first router to point to the second router. Now all incoming connections are sent to the 2nd router and thus your port forwarding & triggering will work again.

So here is a quick example. I log into router 1 and go to the DMZ settings and put the WAN IP address of the 2nd router there. Now router 1 is out of the way for port forwarding and triggering as all incoming connections are now being forwarded to router 2. Now in router 2 I can setup my port forwarding & triggering rules just like normal.

So here is a quick step by step.
Step 1. Login into your Router
Step 2. Find the status page that shows the WAN/Internet IP address and write it down. (The Gateway IP will be the IP needed to log into the first router/modem.)
Step 3. Log into the first router/modem now.
Step 4. Find the DMZ page
Step 5. Enter the IP you wrote down into the DMZ page and enable DMZ.
Step 6. Save and you’re done.

Quick Tip: You should setup a static WAN IP address for router 2. If you leave it on DHCP the IP could change thus breaking the DMZ and of course breaking the port forwarding & triggering. This doesn't happen very often, but it is always a possibility.

If you want to Setup 3 routers at home. Here is my plan to setup. Please let me know if it make sense.

1.    SMC. It is a modern with router. It locates in the first floor, Rogers cable connected to this router. It is the main router to connect outside. I turned off the wireless on the router. It has 4 ports connected to SMC all with wires. First one connect to D-615(second router) Second one connect to D-815(third router) Third one connect to WD Mybook live(NAS HHD) Fourth one connect to TV player

2.    DLink 615. It is a wireless router. It located in the first floor as well, but close to bedroom. It has 4 ports, but I only use 3 of them connected to PC. Also there are wireless device need connect to this router as well.

3.    DLInk 815. It is a wireless router. It located in the second floor. It connected with 3 PCs and also accept wireless connection. The signal in second floor is very weak if using D-615 wireless connection.

I setup the SMC to 192.168.0.1 with DHCP, D-615 to 192.168.2.1 with DHCP and D-815 to 192.168.1.1. I cannot get rid of the second router, since SMC doesn't have enough wired port. And I need to D-815 because the signal problem. Wondering if this gonna work? Thanks.

Connect Your DVR to Your LAN

we will assign your surveillance DVR an IP address.  Make sure that your DVR is connected to your network by attaching an ethernet cable to the back of your DVR and attaching the other end to your router.

1. Login to your DVR by pressing the menu button on the DVR or on the wireless remote control.

2.  When you are prompt to enter a password, just press the OK button on the DVR or remote.  The default admin password for the DVR is blank.  If you have already setup an admin password for your DVR, then enter this, then press OK.

3.   From your DVRs System menu, select External Device.

4.   On the External Device menu, select TCP/IP Setup.

5.   On the TCP/IP Setup screen, select DHCP setup and press enter.

6.  On the DHCP setup screen, confirm that the DHCP mode is set to automatic.  If it is not, adjust it so that it is by pressing the OK button. 

7. Select Detect IP and press enter.  The screen should refresh and populate values below.  Note the IP address.  This is the internal IP address that your router has assigned to your DVR.  This is the IP address that you will setup port forwarding for.

8.   After you have noted this IP address, select DHCP Mode and press OK.  The mode will be changed Manual.  This will ensure that your DVR will always be assigned the same IP address from your router. THIS IS IMPORTANT because if you loose power to your router, your router may assign your DVR a difference IP address and you will no longer be able to access the DVR remotely.

9.   Press the menu button once to return to the TCP/IP setup screen.

10. On the TCP/IP setup screen, select IP config setup and press enter.  On the IP config setup screen, confirm the port number of your DVR as seen below.  The default port is 8000.  If your DVR is not set to port 8000, please edit this value to set to 8000.  NOTE: please ignore that the below screen shot shows port 50000.  Port 50000 was used for the last version of the JPEG DVR.

Since most businesses and many households have local area networks (LANs), you will find the task of connecting a security DVR to a LAN is a common procedure. While it is a relatively simple thing for most security equipment installers, it is complex enough to confuse many users, especially users who have never worked with IP numbers before or have never worked with LAN topology.

Let's begin by identifying your LAN topology. To do this, locate your

1) security DVR,

2) the router attached to your security DVR and

3) a computer/workstation that is attached to the same router. It can also help if you locate

4) the modem  (or router AND modem)  that connects to the internet outside your home or facility - it is usually the first piece of hardware attached to the internet cable the comes through the wall. If you don't have #3 (computer attached to the same router shared by your security DVR), create one now and verify that the PC/workstation has a working connection. If you can't find or locate #4 (modem that provides connection to the internet) don't worry about it at this point since locating it may not be necessary.

Some typical network topologies are shown below. Figure #1 represents a simple network topology you might find in small business, while figure #2 represents a very simple network you would find in many homes. (Figure #2 actually represents the bare minimum hardware & connections you need for remote DVR monitoring/programming.).

Make sure (verify) your network connection is active and your PC can connect to the internet without any problems. Start at your PC and do the following:

1. Go to the COMMAND PROMPT. Different Windows versions have different ways of getting a COMMAND PROMPT. Most Windows versions let you reach a command prompt by going to START, then RUN, then type CMD into the window and hit ENTER. If successful you'll see a screen similar to Figure 3.

2.  Figure 3 shows a computer screen with the command prompt, and the PROGRAM FILES folder is open. That location should be fine. Type IPCONFIG/ALL and hit ENTER.  You should see a display screen similar to Figure 4.

( If you DON'T see Figure 4, they you are probably getting an error message. You'll need to find the person who installed your OS and find out why it doesn't have essential DOS files - you won't be able to continue this procedure without them.)

IPCONFIG is a standard Microsoft DOS command. You can read all about it at the official Microsoft website (http://technet.microsoft.com/en-us/library/bb490921.aspx), if you want. When you use this command as described here, it will report the computer's IP numbers so you can record them for your records. It does NOT change any settings or perform any kind of configuration process.

3. Write down the IP numbers shown under

IP ADDRESS (192.168.1.100),

SUBNET MASK (255.255.255.0),

GATEWAY (192.168.1.1) and

DNS SERVERS (206.222.98.82, 216.199.46.11, 206.222.98.82 - this particular computer has 3 DNS SERVER connections) and label them.

NOTE: Some versions of MS Windows will display IPv4 ADDRESS and an IPv6 ADDRESS - you want to use the IPv4 ADDRESS numbers.

4. Now get the IP Address of the security DVR. Got to the VRR andaccesssthe programing menu and get to the NETWORK settings area. Find the option that says DHCP (Dynamic Host Configuration Protocol) and ENABLE it..

5. Still at the DVR, write down the IP addresses it shows in the DHCP screen. Now turn OFF DHCP (or DISABLE it). If the IP addresses shown did not change, go to the next step. IF THEY DID CHANGE, re-enter them in the fields shown (DO NOT enable, or turn on, DHCP again).). If the IP addresses shown did not change, go to the next step. IF THEY DID CHANGE, re-enter them in the fields shown (DO NOT enable, or turn on, DHCP again).

6. Note the PORT NUMBERS shown in the DVR NETWORK screen. Write them down.

7. Test your configuration. Do the following at the PC/workstation that shares the same router as your DVR:

·   Get to the COMMAND PROMPT.

·   Type PING [IP Address], hit ENTER. (In our example the IP address is 192.168.1.100)

·   If you get a REPLY message, it communicated. If not, and you got a TIME OUT message of any kind then check your settings.

8. Your DVR has CLIENT SOFTWARE or REMOTE VIEWING SOFTWARE that was included in the box. Locate it and install it on the PC/workstation.

·   If your DVR has a webserver you can use IE Browser to communicate with the DVR - just type in the DVR IP Address in the URL bar of the browser.

Port Forwarding & Accessing Your DVR from Outside Your Network

To set up external (remote) viewing of your DVR and attached cameras, you will need to access your router. Refer to the router's User Manual to learn how to set port forwarding. If you can't find it, look here http://www.portforward.com/english/routers/port_forwarding/routerindex.htm. All routers have a different method of setting up port forwarding so it's impossible to instruct you here.

Program the router so that when it gets an internet request for the IP ADDRESS of the DVR it will refer (or activate) to the PORT NUMBER of the DVR (you wrote these numbers down earlier, right?). Normally most routers have a field for each physical connection and it will be obvious where to place the IP and PORT NUMBER information. If you can't find how to access your router, look at the router closely and make sure it is indeed a router and NOT a switcher. It should be ok if it's labeled ROUTER/SWITCHER but if it is an older piece of hardware and just says SWITCHER, discard it and get a true ROUTER.

Test the connection from an network external location. If the IP numbers and Port Forwarding numbers are set correctly you should be able to receive streaming video.

Using IE Browser VS Client/Remote Viewing Software

If the DVR has a webserver, then you can use IE Browser to connect to the DVR. Put the DVR IP address in the URL bar of the browser (like http://192.168.100.200, etc).

If the DVR does NOT have a webserver, then you will need to install the client/remote viewing software (that came with the DVR) on the PC/workstation you are using to view your security installation. The Client Software (or Remote Viewing Software) gives you additional features, such as ability to program motion detection, etc., that the IE Browser can not provide. Since each surveillance DVR has it's own client software, you'll have to refer to the software manual for help using their software.
