It sounds like what you are after is ip aliasing, as well as ip masquarding.
Set it up so that your link to the internet looks like 3 diferent interfaces,
and set up the rules so that stuff from 192.168.1.0/24 goes to someting like
eth0:0, 192.168.2.0/24 goes to eth0:1, ect. I am not sure of the format for
ipchains, but for ipfwadm you would do something like
ipfwadm -F -a masquerad -S 192.168.1.0/24 -V 60.10.20.51
ipfwadm -F -a masquerad -S 192.168.2.0/24 -V 60.10.20.52
ipfwadm -F -a masquerad -S 192.168.3.0/24 -V 60.10.20.53
or
ipfwadm -F -a masquerad -S 192.168.1.0/24 -W eth0:0
ipfwadm -F -a masquerad -S 192.168.2.0/24 -W eth0:1
ipfwadm -F -a masquerad -S 192.168.3.0/24 -W eth0:2
I hope this gets you pointed in the right direction... Someone
with more experence with firewalls then me should be able to give
you the right format...
