What's the problem with getting three static addresses, one for each
of the modems? Of course, it'd be more expensive, but, usually, ISPs
don't allow more than one simultaneous connection to them even if
you have a dynamic ip address, so you'd have to pay for three dynamic
ip accounts anyway.

This is the worst thing of it.

Well, for me it crashes even with IP masq. There is no reason why it
should not.

And the disadvantage that if you want to connect to your computer
that is on dynamic ip address, you also have to find it first ...
This makes having a WWW server on it virtually impossible. (Without
a service like dyn.ml.org)
Conclusion:
It's always better to have a static IP address. Usually,
it costs you more money, too.
