How do I configure to remotely monitor a DVRC264-16ME with Apple based computers?


Remote access setup is the same a with a PC. Each router is different but the apple versus PC issue is not. Once remote access is setup, you will access the DVR interface using the IP address you have chosen. If you need help setting remote access up, call us. We offer the service for minimal cost. If you want to do it yourself which can take hours and will possibly make you pull your hair out, then research your specific router model number and make sure you port forward the proper ports that your DVR or NVR asks for and insert them into your router firewall, pointing them to your DVR or NVR's local IP address.

How to convert local ip camera addresses to ip addresses to connect from internet


depend on what brand and type of the ip camera that you use.

in order to be able to access from internet:
- you need to use a router that connect to a switch and the camera
- the router must have UPnP Feature & Port forwarding.
- just in case your public ip address is dynamic, you will also need a ddns for redirection.

The basic concept is, you have to configure the network setting of the camera according to the router as a gateway.
usually, in the network setting, you will find a http port number.
change this number from default ( 80 ) to another number from 0 to 65535 ( example 50010 or 40000 , you can choose freely, it's recommended to use port above 50000 )

then find the portforwarding function in your router, then set the port number to the ip address of the ip camera.

if it's successfull, you can directly access the camera from the internet by entering your public ip address and the port number on your browser.

for example : http://itcomm-streets.viewnetcam.com:50001 << my ip camera demo unit.

How to forward port for a IP camera on a Huawei 655b modem ?


You can't port forward on a modem. On a router, yes. You just need to set the a static IP on the camera outside of your DHCP range. Then select a port above 1024 and set that port to point to the static IP. You should only need to port forward UDP. Optionally you would want to setup a dyndns account since your public IP from your ISP is dhcp and therefore doesn't always stay the same.

Cable modem internet works when directly plugged into desktop, but when run through the router, no connectivity


Most cable Internet Service Providers (ISP) use a Media Access Control (MAC) Authentication to establish Internet connections for end-users. A MAC address is a unique 48-bit (6-byte) integer that is attached to an Ethernet NIC for each computer. To set-up your Linksys router to a Cable ISP, you have to do MAC Cloning. MAC Cloning is a procedure which enables a router to copy the MAC address of the PC that's registered with the ISP.
To setup a Linksys router with Cable connection you need to perform five steps:
  1. Verifying Internet Connection
  2. Connecting the Devices Together
  3. Checking the Router's LEDs
  4. Configuring a Linksys Router for a Cable Connection
  5. Power Cycling
NOTE: Before proceeding, use the computer that can go online when connected to the modem and follow the steps below.
Verifying Internet Connection
Connect the Broadband modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active. If it is not, contact your ISP. If it can go online, the PC connected to the modem is the one that's registered with the ISP.

kb4682-001_en.png NOTE: The image may vary depending on the computer and modem you're using.
Once an active Internet connection is established through the modem, connect the modem and the computer to the router by following the instructions below.
Connecting the Devices Together
After ensuring that you have an active Internet connection, connect the modem to the router's Internet port and the computer to any of the four Ethernet ports. For instructions, click here.
After connecting the devices, check the LEDs by following the instructions below.
Checking the Router's LEDs
The Linksys router's front panel will indicate the status of the connection. After connecting the broadband modem to the WAN or Internet port, the computer to an available numbered port and powering on the router check the lights on the front panel of the router. For instructions, click here.
After checking the router's LEDs, configure the router for cable Internet. For instructions, follow the steps below.
Configuring a Linksys Router for a Cable Connection
kb4682-002_en.png For Telstra Cable internet users, please contact Telstra to confirm if your internet connection is using DHCP or HB (Heart Beat) signal. There should be no other machine running HB client upon doing this procedure.
Step 1:
Access the router's web-based setup page. For instructions, click here.


NOTE
: If you are using Mac to access the router's web-based setup page, click here. If you forgot your IP address, click here. If you forgot your router's password, click here.


Step 2:

When the router's web-based setup page appears, click the drop-down arrow under the Internet Connection Type field and select Automatic Configuration - DHCP.
(a) If you are NOT using Telstra HB, proceed with DHCP setup.

kb4682-003_en.png
NOTE: If you are a Telstra Cable internet user and you're using WRT120N, WRT160N v1, WRT320N or WRT610N, please select Telstra Cable.
(b) If you are using Telstra Cable, proceed with the following setup. Obtain your user name and password from Telstra. Please disable any HB client that might have been previously running on the PC after the router is configured.

Step 3:
Click kb4682-005_en.png.

Step 4:
Click MAC Address Clone.

Step 5:
Select Enabled and click Clone My PC's MAC.



kb4682-007_en.png




Step 6:

Click kb4682-012_en.png.


Step 7:
Click Status. Check the value of the Internet IP Address. If the Internet IP Address has numbers, this means the router has been properly configured. You should now be able to access the Internet. If you're not online, perform a power cycle to synchronize the router with the modem. For instructions, click here.




kb3687-005_en.png

kb3687-006_en.png



NOTE:
If the Internet IP Address is all zeroes (0.0.0.0) click kb4682-008_en.png first then click kb4682-009_en.png. If the Internet IP Address is still all zeroes (0.0.0.0) perform a power cycle. For instructions, click here.
If the IP Address starts with 192.168.1.xxx or if it has the same first three numbers (octets) as the router's IP address, change the router's LAN IP address to a different LAN segment. For instructions, click here.
Once the router is configured, perform a power cycle. For instructions, follow the steps below.
Power Cycling

Step 1:
Shutdown the computer.

Step 2:

Unplug the router's power cable.


Step 3:

Unplug the Broadband modem's power cable and wait for 30 seconds.


Step 4:

Plug in the Broadband modem's power cable and wait for its lights to appear stable.


Step 5:

Plug in the router's power cable once the modem's lights appear stable.


Step 6:

Power on the computer on and test the Internet connection.
NOTE: If you're not online after performing this procedure, you may need to upgrade the firmware of the router.

Cant setup or connect to internet through router


Different ISPs require different configurations. If you have a Linksys router, such as the WRT54G, there are 2 ways on how you can configure it, either by running the Setup CD or by doing manual configuration. This particular router has its own web utility and you can access it by typing its IP addres on your web browser, ex. http://192.168.1.1. By default, it doesn’t have any username and its password is admin.

Once you’re inside the setup page, you can configure now the router for DHCP, PPPoE or STATIC IP settings. For DSL customers using a PPPoE account, some modem needs to be configured into BRIDGE MODE first and then the router will be set to PPPoE with the correct username and password (given by ISP). If your a DHCP account, modem doesn’t require any configuration. It will work with its default setting and the router would be set to DHCP. Once done, powercycle your devices to establish internet connection.

ADSL ISP provides same address for IP and Gateway


Can you manually change the WAN IP on the router?  If so, give it an IP like 123.12.167.5 and set the gateway address to 123.12.167.1.  If it asks for a subnet mask, give it 255.255.255.0.
If she has a Linksys router, you may need to change the operating "MODE" on it.  A lot of Linksys routers have 2 modes of operation---Router mode and Gateway mode.  For her configuration, make sure the Linksys is in Gateway mode.  This will fix the NAT problem.

Cheers!

Dual Routers?


Disable DHCP in the router. Connect the modem to a LAN jack on the router. You'll have 3 LAN ports. If you need more ports, buy a hub. (You can change the default IP address on the Linksys, but you can't forward through 2 NATs.)
