Hi all,
I have been reading round (man pages for ipfw, m4, etc, and Google), but
can't seem to find what I'm looking for...
I have managed to get our departmental intranet site migrated from Win2K
to FreeBSD 4.6.2 (yay me - I did good ;-), and am now having trouble with
ipfw. I want to use a macro to prevent large groups of networks and
hosts from connecting, but I've drawn a blank with the syntax. I know I
can use m4 or cpp, for example, but I cannot fathom the syntax necessary
to establish the macros.
From the ipfw man page, I see this is possible:
ipfw add deny ip from netgroup1 to ${myip}
Defining netgroup1 is where I get stuck! I know I need to predeclare
the macro, but never having used m4 or cpp I dunno what I'm doing, and
unless I've become totally blind, I can't see examples in the man pages.
Anyone have any pointers to some docs online I can look at, or example
rules I can rip off? Or even a "reread the man pages, you twit, there's
examples aplenty" would be OK ;-)
TIA,
Dan
