Public Internet line on static lan

Vinken · Jan 7, 2015

Hello Community!

I have the following setup:

Ik have several beamers and media-players in a LAN all on static ip. There is one main control computer that tells the media-players what to play. They are all connected over a SP200 cisco switch. all in range 192.168.0.

What i want is to access the control pc over the internet so i don't have to drive over there every week

But i don't want the rest to connect to the internet.

There is no internet in-house. BUT we can get a internet connection from the neighbors across the street. So we made a point-to-point across the street. Internet works perfectly! BUT it's connected to port on the router that is also used for public guest internet. It's DHCP is enabled so i get a 192.168.1. ip. All my device freak out and stop working if i put the utp in the switch.

The next problem is that i can see all the connected devices from the neighbors. And if i can see them they can see me. Don't want that.

How can i get internet connection on the control pc without being afraid that they can mess up and access my own network.

TNX in advance! :wahoo:

Add a second ethernet card to the PC. Connect that to the "public" connection. You can try DHCP but you may have to manually configure the network interface on the PC.

Oh my...so many things wrong with this.

1.

You are on their network.

2.

That is entirely up to them.

You have their express permission for this?

You won't be able to do this without

1. Changing you device IPs to be on their network. This means using DHCP to avoid IP conflicts.

2. Setting up port forwarding on your neighbour's router to be able to access your PC from the Internet.

3. As mentioned, you must have permission from the neighbours to access their WiFi network (perhaps the "port on the router that is also used for public guest internet" covers this?) - without this you are committing a serious criminal offence.

I'm happy, in an emergency, to let my neighbour use my WiFi, but no way would I allow them to set up port forwarding on my router. And once you've done this, is it really a good idea? If you can access your computer from the Internet then so can millions of people around the world; some of them are very clever and some of them are not very nice. And then there are those who are both clever and not nice.

I Know.

The projectteam asked for this solution

3. You have their express permission for this?

Yup! It is a fellow company that is in the projectteam.

kanewolf :

My thought also. And then hide all ports except ports for example TeamViewer.

Yep

Allowed

Totally agree!
