Hi there.

195.249.122.1 =3D FreeBSD = 2.2.6

195.249.122.2 = =3D=20 Win98

195.184.60.2 =3D DNS

Why is it that when I set "ipfw = add deny=20 all from 195.249.122.2 to 195.249.122.1" I'm still able to ppp to=20 195.249.122.1 from to the computer I just denied?? If I ping = 195.249.122.1 from=20 195.249.122.2 it says "request timed out" as it should, but = when I do=20 anything that has something to do with ppp the modem just dials as usual = &=20 everything "works". Why is that? Isn't "deny all" = suposed to=20 filter out all packets from 195.249.122.2 letting nothing = through?

- thanx up ahead!
