One Router, one switch, three LAN - how can it not see each other
Posted on 2005-03-06
I use D-Link 504G and a 16 Port Edimax switch. I'm trying to connect up three companies on the same switch and router. Each of these companies has their existed LAN.
The computers they use are Windows XP - Home Edition and Professional, Windows 98.
I turned DHCP server in the router off, so that I can assign each company's computers seperate IP address.
Company A - 192.168.0.1/16
Company B - 192.168.1.1/16
Company C - 192.168.2.1/16
Default Gateway - 10.1.1.1 (router gateway)
Theorically it should not see each other. But it did!
All those computers have no problem using broadband internet via the router. They can see each other.. even those are in a different workgroup.
How do I stop them from seeing other computers in the different workgroup?
