Port Forwarding Instructions
Port Forwarding Instructions.
1. Find the gateway (router) IP address using command prompt.
i. Start -> Run(Search Box) -> CMD
ii. In the command prompt window, type ipconfig then press enter.
i. System Preference -> Network ->Advanced -> TCP/IP
2. Type the gateway IP address into the browser and log in to the router using the router’s user name and password
a. Apple’s Airport requires Apple software to configure. (Airport Utility)
3. Find the IP address and the default Ports on the DVR
a. If the DVR is on static IP address, change it to DHCP first.
b. Port numbers are usually listed under Network settings.
i. For GW93xx, GW97xx, The ports are:80, 9000
ii. For GW21xxE, GW22xxE/EP, GW24xxE/EP, The ports are 80, 8101, 1935
iii. For GW5xxxCVI, The ports are: 80, 37777
iv. For GW17xxTVI, GW27xxTVI, The ports are 80, 6036
4. On the router’s setting page, navigate to the settings for port forwarding.
a. Depends on the router, the settings might be in different areas.
i. Most of them are under “Security” , “Firewall”, or “NAT”. On some of the routers, port forwarding is referred to as “Pin Holes” or “Virtual Server”
b. The settings you need to put in differ on the type of routers. Below is an example of one:
In this case, Application is the name of the port forwarding rule, Protocol is TCP. Source Net might be named something else in other router, in this case it refers to what IP address can access the ports. You can leave this part blank. Port From and Port To refers to the port number you want to forward. “Port From” and “Port To” don’t have to match, but “Port To” must match the DVR’s port number. IP Address field is where you put the IP address of the DVR.
c. If there are two routers in the network (referred to as double NAT), you will need to forward the ports from the first router to the second router, then set the port forwarding rules on the second router.
5. After you set up all the port forwarding rules:
a. Set the IP address on the DVR from DHCP back to Static
b. Go to canyouseeme.org and test your ports.
6. If the ports are opened:
a. You can test to see if you can see DVR using the public IP address
i. If you can’t see it with the public IP address in the local area network, your router does not support loopback function. You will need to use local IP address to access the DVR
1. On smart phones, you will have to turn off wifi to test the public IP address again.
7. If the ports are not opened when you use canyouseeme.org to test the ports:
a. You might need to configure the firewall settings on the router.
b. Make sure that in two router environment, the ports are forwarded in the first router.
c. Make sure the gateway address on the DVR is the router’s IP address (if you set it to DHCP in the previous step this should not be the problem)
d. In rare cases, your ISP might be blocking the ports. If all the settings are correct, you will need to contact you ISP and have them open their side.
