Why can't you make mountd on Ultrix 4.X reject mount requests from 
non-privileged ports? turning on "nfsportmon" in the kernel doesn't
quite do the job properly. Things that make you go hmmm...

Install a good portmapper so that remote hosts can't easily find what port
mountd is on.  A better solution is to make sure that your routers kill
all NFS packets from remote nets.  

Any idea what I should block on my router to do this?  I have a cicsco
router if that's any help.

Also, does anybody know of a mailing list or FAQ for cisco setup.  I find 
their manuals cryptic.
