Maybe my description was not so clear: I want ABC.DEF.75.* to be behind
my firewall (75.1-13 are my servers, 75.16-253 are other PCs in my
building), everthing else I consider as 'net', and this is a campus netwerk
ABC.DEF.XXX.YYY, with XXX e.g. 70, 71-74, 76-79, 80, 81, etc...
and also the whole rest of the 'Internet'.  143.129.70.201 is the address
where everything (either from the campus or from Internet) is routed to if
it has a ABC.DEF.75.* destination address.

(Sorry, I may have referred to my campus network as my 'local network',
  'local' was not the appropriate word to use, since in fact it just
the opposite of what my 'loc' zone is...)

Sorry, this is a bit too high-brow, I am afraid I don't grasp what
you mean..
