I bought your book Building Linux and Openbsd firewalls. And I really
enjoy it (I find myself going back and back for reference material etc).
But I'm still looking for more info on ipf.rules & ipnat.rules files.
I'm mainly interested on doing the redirects (rdr) i.e. to a
web/ftp/mail server on the internal network. Do you know where I could
find any further, or perhaps more detailed info?
Thanks in advance
P.S. Please keep on writing, Your efforts are really enjoyable.
