I can't say I've ever used linuxconf.  AFAIK, (correct me if i'm wrong!)
linuxconf just calls ipchains with the appropriate options to add
ipchains rules.  Reading up on IPChains is highly recommended, and there
is an EXCELLENT howto on linuxdoc.org on how to use it (I know it's
excellent because i've read it a lot :).  I'm guessing the "blocking"
rules here, but without knowing what linuxconf does and how it does it,
I can't really help ya.

You won't be able to change permissions with chmod, as vfat drives don't
know what the hell file permissions are (permissions? EVERYONE has
permission! :)  You'll need to read up on the "mount" manual page, under
the filesystem-specific options.  You'll probably need to use the mount
command "mount -t vfat -o umask=0777 /dev/hdb1 /bigdisk" where /dev/hdb1
is the partition you are mounting and /bigdisk is the mount point.
