Yes, in general, custom chain and RETURN target can help to simulate
"or" operator. But in your case, you should be able to combine "! -o lo"
and "! -d 192.168.0.0/16" matches to do what you need.
On the other hand, I prefer to explicitly state what I want to
masquerade rather than masqeurading everything with some exceptions.
