[COLOR=blue]If a server can connect multiple users to the internet via one dial-up-connection.Is it possible to configure a machine as a server using one of microsofts products,have it open a connection to the internet,then make miltiple connections thru the same connection and have the available connections placed on a VPN or LAN for access at the same time by any user.Does it use multiple frequencies to send/recieve the different requests or is some other technology used.
Yes... it's called Internet Connection Sharing - ICS.
If the machine connected directly to the net is running XP you can support Connection Sharing on different subnets - i.e. if you have ethernet and wireless networks computers on both parts can share.
But otherwise, you are restriced to one subnet.
However, I don't recommend ICS. Because: 1. It can be a bit hard to set up 2. The main internet machine must be on all the time 3. Sharing only makes sense of you have a reasonably fast, always on connection 4. In which case you should have a hardware firewall 5. And hardware routrers with integrated firewalls are now cheap.
