Hey,

Have you guys seen this error message before.  Especially
at home when connected to a DSL or Cable Modem?

Aug 24 08:07:50 gw natd[130]: failed to write packet back (Permission
denied)
Aug 24 08:08:11 gw last message repeated 3 times

After reading a lot of postings, I found a post from
a FreeBSD core developer who blamed this error message on
his cable modem provider and stated that it looked like the
ip to mac was not mapping correctly.

So I added the mac address for my dsl modem manually

	arp -S x.x.x.x 0:10:66:0:34:72

This seems to have stopped the message completely.  I have
been running the machine with the change for a couple of
hours and have not seen the message again.

I am open to suggestions as to where the command should 
be put (ie:  which file to edit).

Kasey
