I have. It does not work either. It worked with SuSEfirewall(1), but now
with SuSEfirewall2, the examples explicitly state that the eth0:0 syntax can
be used.

At this point, find your input hardly constructive. It seems as though you
are trying to show everyone else what a great network administrator you are,
rather than seriously trying to add to the pool of knowledge.

I have a script that works that I can use until I get SuSEfirewall2 working,
but that is not an optimal configuration, as it does not integrate nicely
with the other processes, but is rather tacked on to the booting process as
an afterthought. In SuSEfirewall, masquerading is performed on the indicated
interfaces, but limited to a subnet specified with another variable.
