Internet Connection Sharing in Home Network?

[Izgir]

Configure the usb adapter to DHCP, and configure the ethernet adapter using a static ip address. The ethernet adapter will need to be on a separate network from the usb adapter (usb adapter = 192.168.1.10, so configure the ethernet to 192.168.0.1 for instance). Once that is done, share the connection, disable firewalls. Now you will want to configure computer B to have an ip address of 192.168.0.x (where x is anything from 2-254). Set the default gateway on computer B to 192.168.0.1, and you will need to hardcode your dns server into computer B as well (this can be found by going to start -> run -> cmd -> ok and typing ipconfig /all). So the computer B configuration will look like this in the end:
IP address: 192.168.0.X
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Servers: same as usb interface on computer A (or you can use a public DNS server like 4.2.2.2)

once all this is configured, make sure you can ping 192.168.0.1 (start -> run -> cmd -> ok type ping 192.168.0.1)
if you recieve replies, try pinging out to your DNS server address. If the DNS replies, then you should be able to surf w/o any trouble.

I run this particular configuration on my network, where my computer A goes to a switch connecting to my other computers (we'll say B, C, D and E), and the nice part about it is you can monitor all traffic going across your internet connection
