Okay..apparently I don't know excatly how your setup is.

Let me make a small drawing:

internet
+-+--------------+----+
  |           GATEWAY
+-----+ 
|modem+--------------+
+-----+              |
                     |
           |---+-----+---------|
           |   |               |
	H1    H2              H3

The modem acts transparently.
H1 is the host you want to give internet access. It should DHCP
from some host positioned after the modem.
H2 and H3 are local hosts that should be able to communicate with H1.
They will not have internet access.

H2 and H3 are assigned addresses (by you), in the 10.0.0.0/8 range.
Is that correct? If you have more info, please provide it.

FreeBSD will too..the question is HOW.

You could help me by telling how to mconfigure Linux on your setup.
