Thanks for the tip. I'm getting closer, but not sure of the correct syntax.

home computers (4)     firewall           wireless          internet
192.168.2.*                                bridge (**)          ^
  ^                        ^                4.2.2.1             |

  |          eth1          |       eth0      |                  |
  --------------------------------------------------------------
           192.168.2.1         4.2.2.2 (**)

** - IP address' to protect the guilty

What I want to to, is to change eth0 from my ISP's address 4.2.2.2 to
a "private " address 192.168.1.2

So far, from the command line and in /etc/network.interfaces, I can 
bring up eth0 using the following;

ifconfig eth0 4.2.2.2 netmask 255.255.255.0 broadcast 4.2.2.128 up
route add  default gw 4.2.2.3

this will allow my access to the internet.

I've been pointed to the program - iproute - which appears to get me
closer than I was yesterday at this time.

I've been trying to use the following, with no success;

ifconfig eth0  192.168.1.2 netmask 255.255.255.0 broadcast 192.168.1.255 up
ip route add 4.2.2.1/32 (bridge) dev eth0
ip route add default via 4.2.2.1 dev eth0

I've tried pointing to the ISP's gateway IP address' but it complains
"network unavailable"
