The Default Technicolor TC7200-U Router Username is: admin.You should see a box prompting you for your username and password. If all goes well you will see the following screen: Screenshot of Technicolor TC7200-U. The default Technicolor TC7200-U IP Address is: 192.168.0.1Īfter entering the IP address of your router you can simply press enter.
Find the address bar in your router and type in your router's IP address. It should look something like this: Browser address barĪbove is an example of what a web browser address bar looks like. Open up your web browser and find the address bar. It usually does not matter which browser you choose to use. This can be either Chrome, Firefox, Internet Explorer, or Edge. Your router has a web interface, so you will login to it using your web browser. Now we are going to login to your Technicolor TC7200-U router. Or, follow our Static IP Address Setup guides.Īfter setting up a static ip address on your devices you need to login to your router.Recommended - Our free program will setup a static IP address for you.This ensures that your ports will remain open even after your device reboots. I really, really hope that I’m wrong, for the sake of all things holy, but it would perfectly explain the behaviour described above.It is important to setup a static ip address in the device that you are forwarding a port to. This brings me to the conclusion that somehow Cablecom is NATing my connection. I cannot find my public IP address anywhere in that admin interface, so I just had a quick look what the outside world sees me as, and I see an address in the 31.10.128.0/17 range, which seems to be part of “upc cablecom GmbH” (which is probably fine). This brings me to my second question: Do I need to do something more than just click on “save” in order for the forwarding rules to take effect?Īnd last but not least, in the main status view, there is a line “CM IP Address”, with an IP address in the 10.0.0.0/8 range, which I assume is *not* my public IP address.
My first question is: What does this mean: “In DS-Lite mode, IPv4 forwarding is only allowed for single port settings”?Īnyway, after that message I decided to forward just a few selected ports, to test (as seen in screenshot 2), but somehow my packets don’t get passed on to my router behind (I tried a netcat on port 1234, but nothing would happen, and even iptables doesn’t give me any indication that any packets other than the ordinary broadcast packets are arriving).
I would like to forward all ports from the Technicolor TC7200.U modem to my router, but as soon as I try to forward a port range of more than one port, I get a message as seen in screenshot 1.
