This is mostly true, I'm afraid.  (There are some exceptions - such as
the case where you have an 802.1q-capable switch and NIC, where you can
set it up as a trunk line and route between vlan interfaces - but if
you know enough to set that up and make it work right you wouldn't need
to ask this.)

It *is* possible to have a single-interface machine route between
different subnets running in the same broadcast domain ("on the same
cable", except that these days Ethernet isn't a bus technology any
longer, so the term is inaccurate).  This still inflicts most of the
problems of not routing, so it's of questionable value.  (It may be a
right answer for you, depending on why you want to route.)

I'm not clear what you're trying to end up with - that is, what problem
you think turning your SE/30 into a router would solve.  Most of the
scenarios I can imagine end up with your box being not just a router
but also a NAT system (or an application-level proxy, in which case
it's not really a router in the usual sense of the term).

I can't see any reason, except possibly performance, why your SE/30
would be unable to handle what your G4 can...but that's speaking
conceptually; whether the software can do it out of the box is a
completely different question.
