If you are using the black Technicolor router that brsk installed, please take a look at this article.
By default, all of our residential broadband customers are allocated a private IPv4 address which is translated to a public IPv4 address. This means that port forwarding isn't possible, as you won't be able to reach the private IPv4 address over the Internet. This technology is called 'Carrier Grade NAT' or CGNAT, and has become commonplace in the broadband industry due to the dwindling supply of public IPv4 addresses.
To read more about this, please take a look at this article.
Most people won’t need to worry about port forwarding, however, if you’re wanting to access a device that’s on your local network remotely then you may need to open some ports to be able to do so.
To setup port forwarding, follow the below steps.
These instructions are for the Icotera i4850-00 provided by Brsk.
Before you begin port forwarding, you will need the following information:
Port number (Between 1-65535)
Protocol (TCP, UDP or Both)
IP Address of your device to port forward to
Note: To avoid future issues with port forwarding, we strongly suggest you set a static IP on this device. To do this, please consult the manual of your device
Log into the Icotera router by opening up a browser on any device and entering in 192.168.12.1 to reach the login page for the web UI of your router.
The default credentials for the Web UI are:
Username: admin
Password: admin
Once logged into the web user interface of the router, navigate to Port Forwarding under Services in the left hand panel.
Ensure “Enabled” is ticked.
Here you can create port forwards, depending on your needs, by entering:
Name: Enter the name for this port. This is only used for identification.
Protocols: Select either TCP, UDP or both depending on what your service requires.
Ext. ports: Enter the port number to forward into the first box.
Int. IP: Enter the internal IP address of the device to forward the port to.
Int. port: Enter the port number to forward into this box.
Loopback: Also known as hairpinning. Check this if you want to use this port forward from inside your network. If you’re unsure, rather check this box.
Repeat from step 3 for each additional port you need to forward.
Press “Apply” at the bottom of the page and wait for the settings to apply.
Press “Continue” once the settings have been applied.
Press “Save” at the bottom of the page if you’re happy with your settings.
DMZ
We only suggest you use a DMZ if you are confident in knowing what you are doing. This is because utilising DMZ significantly heightens the risk of security issues, as DMZ exposes an entire host on your network to the internet. If you aren't entirely sure if you should be using a DMZ, then it's best not to.
To enable DMZ:
Under Services, press DMZ
Check the Enable box
Enter the IP address of the device you want to enable DMZ on
Enter a description for the device
Press "Save" and then press "Apply"
DMZ is now enabled on that device
