>ok...  here is a picture

First thing, don't use tabs in ASCII diagrams, they
won't look right on all platforms

Second, it wasn't very obvious what you were 
trying to diagram:

Is this right:

               Alpha
     -----------------------
     Eth1               Eth0
129/147.131.140      192.168.1.4
      |                (MASQ)
      |                  |
  Internet               |
129.147.131.140          |
                         |
                         |
+---+-----------+--------+-----------------+
    |           |
Sun Classic     |
IP: ???         |
                |
             Pentiun II
             Eth0:  192.168.1.5
             PLIP0: 192.168.2.1
               |
               |
             Laptop
             PLIP0: 192.168.2.2


If this is right, I'd recommend to directly
connect the laptop to the main Linux MASQ box.
This will make things MUCH easier.  If this isn't
a possibility, you'll have to:

        1) Set up a static route on the MASQ box
           to point the 192.168.2.x network to
           192.168.1.5

        2) You'll need to enable IP forwarding on
           the P-II

        3) You'll need to enable a simple IPFWADM
           or IPCHAINS rule to forward 192.168.2.x
           traffic from the ETH0 to PLIP0 interfaces

        4) You might also need to enable proxyarp on
           the Pentium-II's PLIP0 interface.
