TCP/IP Home Networking
and File Sharing Tutorial
Configure Windows XP
with NetBIOS over TCP/IP
-- With two network connections
and internet sharing turned on.
(click small pictures to zoom)

When you use a Windows computer as a network 'sharing' computer by running Microsoft ICS or other internet sharing software, you must be VERY sure that you do not leave file and print sharing exposed to the Internet.
You should have TWO network connections, each with TCP/IP bound to them. One will be the LAN connection (local area network) and the other will be the Internet connection.
Find your "Network Connections" by selecting "My Computer" from the start menu, then select "My Network Places" and finally select "My Network Connections".
First, Right click the network card that is your INTERNET CONNECTION and select PROPERTIES.  In the picture above, the INTERNET CONNECTION is my 3com connection - I can tell because I have internet sharing enabled so i can see the little the little hand on the icon.  Ensure that only TCP/IP is bound to the Internet connection - we DO NOT want file sharing enabled on connection
Next, Right click the network card that is your LAN network card and select PROPERTIES.  In the picture above, the LAN connection is my wireless connection.  Ensure that all of your services are checked - we want file sharing enabled on this network card.
Next, select the "Internet Protocol (TCP/IP)" and click Properties.
You should now see a screen like the one below.  If you have a network that uses a STATIC IP ADDRESS schema you will see information here.  Most likely, your screen should look just like this.
Next, click the Advanced Button
Select the WINS tab.  Under the "NetBios Setting" area, select the "Enable NetBIOS over TCP/IP"
Finished with this computer

Re: Trouble sharing a printer through wireless internet
I've been having the same problem with no luck so far. I've tried ticking and unticking settings in every possible combination without luck. It's weird because everything was working fine until I had to reinstall the whole OS and now it is just NOT working. The other 3 computers in the workgroup read each other fine, but mine seems to be lost in a parallel universe. Can't share a printer, nor anything else, except that wifi internet is working perfectly. I'm running on an IBMt41.
Will warmly accept any light on this issue.

Re: Trouble sharing a printer through wireless internet
Never mind... it is done. It was a matter of adding some protocols in my laptop.

How?

In Wireless network properties you click on 'Install'. A window will appear. Go for 'protocol', then add. It will show a list of protocols to add. I chose the 'NWLink IPx/SPX...' then 'NWLink NetBIOS' and 'Microsoft TCP/IP version 6'.

Voila! Everything is back to normal.

Good luck!

Two Network Connections
I have two computers on my home wireless network In Network Connections, there are two icons one under internet gateway and one under LAN/High Speed Internet. The internet one is not configurable as described above, when I right click on it I just get one "general" tab. If I share folders on my LAN will they be exposed to the internet?
