routing between different subnets on same if.

[Paul Jakma]

i'm trying to get linux to do routing between 2 different subnets that
are on the same physical interface, because windows hosts don't seem
to accept the redirects.

how do i do it? how do i get linux to fully route between these
subnets on behalf of clients? turn send_redirects off doesn't work,
and nothing obvious shows up with 'ip route help'... (and there's no
man page for it to tell me).

i'm using the RedHat 2.2.16 kernel.

regards,
