I'm setting up a home cable-modem home behind a
Mandrake 7.1 box, I've
checked out the MASQ and Firewall HOWTO's and
understand them. Actually,
I used them with 6.0. Although, a few things have
changed since then. I
also searched the archives and there was only one
posting that didn't
answer this basic question;
What does the default entry in /etc/rc.d/rc.firewall
"echo 1 >
/proc/sys/net/ipv4/conf/all/rp_filter" do? Or more
directly - what is
rp_filter?
Do I need to include this line in the MASQ/firewall
rules provided in
the docs?
Thanks, Victor
