	I have a system running FreeBSD 2.1.5 with the included IIJ-PPP.
I just switched to IIJ-PPP because I would like to do some packet
filtering. I have some configuration questions listed below.

1. What does the configuration parameter "lqr" do? I noticed it was
denied in the sample ppp.conf file. I can't find any reference to "lqr"
in the PPP RFC.

2. In the sample line:

set ifilter 13 permit tcp src eq 110 estab

What does the "estab" descriptor mean? What is it's purpose?

3. Let's say that in the future I may want to block ICMP coming from a
given IP address (let's say 198.133.124.60 as an example). What would
the filter rule look like to block ICMP coming in from that address?

TIA
