What I mean is that nothing works. I can't PING, telnet, ftp or another
other service from a machine on a different subnet (say, 172.16.4.16). I
can do all of these things from 172.8.4.12, which is on the same subnet.

what do you mean by "seems not to work" exactly?

Is traffic from internal subnets not being masqueraded on their way out?
Is traffic between internal subnets being masqueraded when it shouldn't?
Is traffic between internal subnets not being masqueraded when it should?
