Share connection with Mandrake Security

--- Personal,
Where I live I use Ajato via radio. However, one-way access.
It is installed as follows:
I have a network adapter that is connected to the cable. This cable is connected to an external 56K modem UsRobotic. To access I have to access an IP (the cable) and I connect it to internet.
I wonder if the Mandrake Security I can share this connection.
My idea would be as follows: < BR> On the machine with Mandrake Security I would install the cable with the network card and one other NIC would be connected to the network hub. My question is if I could access the IP of the cable through the windows machines and could connect.
I wonder also if it is possible to install apache on Mandrake Security to use it on the network or externally (I know would have to know the IP for that).
