Pros: - once turned on the device provides Internet connection.
Cons: - set up, price.
Pros: - price, allows proper connectivity and data transfer between several computers.
Cons: - doesn't support network address translation(NAT).
Pros: - emulates hardware router functionality and gives IP address and port to the clients to provide Internet connectivity.
- every client needs to use the Proxy server address
- network connection protocols are not being fully supported
What you'll need:
- one additional network(LAN) card, which will act as an outgoing Internet device
- (optionally) hub, if you are willing to share you Internet with more than one computer
First off you'll have to know whether you've been using:
Dial up type of connection (PPPoE) providing a username and password or you are directly connected to your provider(ADSL...) without having to enter username and password every time prior using the Internet.
Open up Start->Settings->Network Connections to see your network cards(LAN).
If you are using ADSL find the incoming Internet connection card(i.e through which the Internet comes in) and right click -> Properties(fig. 1)
If you are using LAN + Dial up find your Dial up connection(and not the LAN card) and right click -> Properties(fig. 2)
Fig 2. LAN + Dial up
On the next screen check the Allow other network users to connect through this computer's Internet connection.
Then you'll be prompted to allow the ICS to change your second(inner) LAN card settings.
From now on it'll have IP 192.168.0.1 and will serve dynamic IP addresses via DCHP to the connected computers(clients).
Other computers setup(clients)
The only thing left to do is to go to Start->Settings->Network Connections, right click on the network card Properties -> Internet Protocol(TCP/IP) - then again on Properties.
...and check both as shown automatically
Protect the shared connection
When all of your computers already have Internet it is important to turn on the integrated Windows firewall:
and then check both: On(recommended) and Don't allow exceptions
Now you are ready. Happy surfing!!!
If you are using home LAN having IP addresses different than 192.168.0.х you'll have to change your DHCP server settings from here: http://support.microsoft.com/kb/230148 by Nevyan Neykov
