Subject: [LARTC] tc filter and fwmark
Date: Mon, 02 Dec 2002 09:55:45 +0000 [thread overview]
Message-ID: <marc-lartc-103882320212520@msgid-missing> (raw)
Suppose:
ipchains -A forward -s inside_net -d 0/0 -j MASQ -m 100
(similar setup with iptables:
iptables -A PREROUTING -t nat -s inside_net -d 0/0 -j SNAT
iptables -A PREROUTING -t nat -s inside_net -d 0/0 -j MARK --set_mark
100)
eth0 = outside iface
eth1 = inside iface
now:
tc filter add dev eth0 ... handle 100 fw
should catch packets marked by the above rule in ipchains (iptables).
Ok. When the packet returns, the masq/nat code will find it in it's
table and demasquerade it (as if by an invisible inverse rule).
Question:
Will the demasqueraded packets also bear the mark 100?
And will
tc filter add dev eth1 handle 100 fw
Work?
I am probably missing something, as I haven't been able to make it work
this way.
Any suggestions, please?
I want to shape the incoming traffic that I route for my inside network
on the inside iface with queues and more complex shaping, rather then
just a plain drop on the outside iface.
Thank you.
