Your network configuration isn't really set up right for masquerading,
then.

In this arrangement, all of your machines are on the same subnet! A
masq box will only masquerade traffic that is being forwarded through
it. However, your masq box can tell that the other boxes on your
network can reach the ISDN router directly, so it rejects their attempts
to forward through it, as an invalid configuration.
Besides, you wouldn't want that configuration, anyway, because it means
all of your network traffic has to pass through the subnet twice, once
to get to the masq box, and again to get to the router. These packets
have a higher chance of colliding with other packets on the network, as
well, so this configuration will cause a drop in performance, even if
you could get it working.
You would do better to add a second NIC to your masq box, and connect it
via a twisted cable (no hub required) directly to your ISDN router, so
that all traffic is forced to route through it. Put your Wintel and Mac
boxes on a different subnet (192.168.1 instead of 192.168.0) and then
you will find traffic flows smoothly for all concerned.
