I currently have ADSL connection, and is looking to switch to VDSL. The problem is that I have a CCTV which connects to the modem, it does port forwarding so the CCTV image can be seen through the internet outside the house. The current modem seems like it can not be moved.

I currently have 2 solutions in head but I am not sure if it will work:

1) Use the modem that Spark provides and use the currently modem as a router which plugs into the modem, the problem is that I am not sure if a ADSL router will work on a VDSL modem and VDSL connection

2)Buy a new modem which has the feature of Port Forwarding and copy exactly the inputs from the old modem to the new modem. The problem with this solution is I am not sure if i can successfully port forward by just copying. I am not very familiar with port forwarding.

Does any one have any solutions for me?
Thanks

How about make and model of modem, maybe it supports VDSL? if it doesn't then a new modem will be required

As for port forwarding on cameras, there is no reason why the new modem wouldn't do this, but again more details on the cameras so a bit of advice on which ports to forward can be given

unless your current modem supports VDSL, you will have to transfer all the settings to the new modem. you will get one from spark when you sign up to a VDSL plan.

it was my understanding that port forwarding cameras wasn't the thing to do as poses security risks.

Now that's irony.

my understanding is people scan your ports, find the one with the cameras on it and then can login and view whats on your cameras, as a lot of people fail to change the password on the cameras

from what ive read the better way to do it is use something like team viewer to login (remote desktop) to your computer and view the cameras over the secure connection

A Vivint system by any chance ? I've tried to explain to them that telling the customer their router needs to fire up a port forward is very problematic and a cloud based platform is the way to go and got no intelligible response. They seemed happy to just point the finger back at the customers ISP/equipment and pretend they are all smart and innocent.

Setting a port forward on an IP camera is an incredibly poor setup, and yet everyday there are security companies going around installing systems with such a setup.

Even if you do change the default password (something most people don't seem to do) there have been well documents backdoors in various brands of equipment that have allowed anybody access, or in the case of DVRs - used them for bitcoin mining.

If you've got a security company that recommended this setup my first piece of advice after changing your modem is to change security companies - followed by telling them to visit Geekzone so we can educate them in networking & basic security 101.

I am not sure which CCTV system im using but it says iTron on the console.

I am currently using a TP-link TD-W8980 and looking to switch to TP-link TD-W9980 maybe.

If i copy over excatly from my old modem to the new modem in the port fowarding setting with the same port plugged for the CCTV may it work?

So can anyone tell me will it work if i use the VDSL modem from spark and plug my old modem into the new modem for router and transmit wifi. The wifi will definately not have VDSL speed? But i am not sure if the internet will go through the ADSL router.

I am also not sure if i use this solution, will the port forwarding work with the old setting, as the router is not directly getting the internet from the wall plugs.

its not vdsl capable but you could have found that out yourself :) its more than capiable of sending data via wifi as fast as vdsl can go. weather your devices can handle it, is another story

you will need a new modem, but when you sign up to a VDSL plan you should get a free modem anyways.

If it aint connected to the Internet (via WAN interface) then it aint doing any routing, that simple. If the VDSL device is doing the routing then it needs the port forwards.

How can your old ADSL device be used as a router in such a setup??, to do so would require it to have an Ethernet WAN interface which it most likely doesn't have.

step one: get VDSL
step two: transfer your setting to new modem if you want to keep the security flaws there
step three: investigate using your TP link as an access point if you so wish

Yes, that's why they supply you with a modem.

While it is usually possible to connect two modems via ethernet, it will not come close to achieving what you want to do.
If you are using port forwards (which as noted above is a poor solution in terms of security), they have to be done on the device that is routing to the WAN, in your case the VDSL modem.

If you insist on using port forwards, just set this up on the new modem - there's very few modems out there where this is not a feature.
