I have installed a CCTV unit plugged it directly into my Router. It has been assigned a static address on the local network, I can now login to the CCTV unit via HTML via the PC.

My router is a BT 2wire.

Private IP details are

The CCTV box now has a static IP of

Two PCs are on the network - one .69 and .70

How would I configure the router to allow me to connect over the internet to view the CCTV. Port forwarding?

Yes, it looks like you need to setup portforwarding for port  80 (http) and/or 443 (https) from your external IP to When you are outside your network, you go to http://<your external intern ip> or https://<your external intern ip>  and you should go to the html page.

For security I would change the incoming port however, a lot of hacking software scan known ports like 80, 25, 3389 etc for trying to break in. You probably can't change your port 80 or 443 at the cctv item s you need port REDIRECTION. Not sure if and how to configure your router but in mine I would config as following:

Set port forwarding
Incoming: WAN1 (internet)
Incoming port: 81 (you can use another if you like, just don't use a well known port, use google)
Destination ip:
Destination port: 80

Now from the outside go to http://<your external intern ip> :81 and you would end up at (:80 is default for http so it normally is left off, I'm just putting it in for clearity)

That's great advice - thanks.

Does anyone have a step by step instructions how to set up port forwarding on port 80 using a BT 2WIRE 2700 HGV?

Took a look at the manual (http://www.2wire.com/pages/pdfs/2701HG_user_guide.pdf) and I think it works as follows:

Hosting an Application- Login into the router
- Click the firewall tab
- Click the Firewall Settings link under the tab to open the Edit Firewall Settings page
- Under 'select a computer' select the CCTV
- Select 'Allow individual applications'
- Select an item containing HTTP or HTTPS (depends on what the CCTV uses) and click ADD
- Click Done

You should be able to access it from the outside. To use port redirection you shoud add a new application profile:

- click the Add a new user-defined application link to open the Edit Application page.
- Applicationname: CCTV redirection
- protocol: TCP (I think)
- Port: 81
- Timeout: use default
- Map to host port: 80
- Application type: None
- Click  'Add definition'

You should now see it under the application list. Now add this application as stated in the first part. This redirect HTTP request from the outside on port 81 to port 80 on the CCTV. You can also do this with port 444 / map to port 443 if you need to use https. This redirect HTTP request from the outside on port 444 to port 443 on the CCTV.

use http://<external ip>:81 or https://<external ip>:444 from the outside to test.
