Windows 7: 2 domain in 1 ETH connection

2 domain in 1 ETH connection

Hi there
How to access 2 networks in one physical ETH RJ45 connection ?

At first I would say it is not possibel but it seems my former colleague did this on a Windows 7 machine.
Having 2 network:
172.31.x.x
10.10.x.x

Can I set a WIN 7 computer to 'see' both networks, without adding a second ethernet card ?

No, I'd say you cannot. However if you have the right router, and the correct version of Windows 7, you might be able to grant yourself access to both via VLAN.

I inherited his PC and it's a WIN 7 Ultimate 32bit.
1 ETH RJ45 connector.
I'm doing some changing on a C# program he made, using ethernetwebCams placed around the network.
The 2 cams has IP in the 10.10.x.x the third has a 172.31.x.x number so has the rest of network internally in the company.
He entered all 3 cams from one connection, at the same time.
I saw it running but not how, since I didn't know at that time they had different IP range.

You can place network cameras on the same network, and of course they'll each have a different IP address, the same way as everything on your network must have a unique IP address.

Usually they would be connected to an ethernet switch, not direct to a computer.

Of course they are not connected directly.
Of course they have their own unique address. -in 2 different ranges.
That's not the problem.

How to get the Computer to see 2 different ranges from 1 network card ?
What about the "alternate configuration" tab ?
Isn't is just and "alternate configuration" in case the "original" doesn't work ?
Or are they in use simultaneously ?

I'd suggest you use a router that can create virtual (VLAN) connections and bridge them to your physical LAN.

For instance the Draytek 2830/2930 series.

It's not a feature you'd find in cheap run of the mill routers.

Hello,

Just add an additional static IP address. Have a static address in each IP ranage. This way you will be able to access anything on either ranges without setting up advanced routing.

To do this do the following:
Click Start> Control Panel> Network and Sharing Centre> Change Adaptor Settings> Double Click Local Area Conneciton> Click properties> Click Internet Protocol V4> Click Advanced> Add an IP Address.

This will work providing you add an IP address that is not currently being used in the range.

"Or are they in use simultaneously ?"
Yes they are in use simultaneously
