Hello!

This arguments never run on my system, but I need this:


#!/bin/bash -x

echo "1"
iptables -t mangle -p tcp -d 0/0 --dport 80 -j MARK --set-mark 2

echo "2"
echo "201 T1" >> /etc/iproute2/rt_tables

echo "3"
ip rule add fwmark 2 table T1

echo "4"
ip route add default via 192.168.21.2 dev eth1 table T1

echo "5"
ip route flush cache


Errors:

debian:~# sh portroute

german at my e-mail addy.

Thank you very much.

To what chain this rule goes? Probably FORWARD
iptables -t mangle -I FORWARD -p tcp -d 0/0 --dport 80 -j MARK --set-mark 2

I think it''s lame to be admin and ask step by step tutorials
Afterall, what is your head meant for?

You''re welcome.

Thanks for the comments!

Sorry, I`m a technical study on a school and newcomer in linux routing, but
I have a project to shaping multiple dual DSL line at school.

The LARTC multiple providers makes the job very well, but I must try control
the traffic per ports (port80 oder port21 and so on).

I have made the changes:
____________________________________________________________________________
__

#!/bin/bash -x

echo "1"
iptables -t mangle -I FORWARD -p tcp -d 0/0 --dport 80 -j MARK --set-mark 2

echo "2"
echo "201 T1" >> /etc/iproute2/rt_tables

echo "3"
ip rule add fwmark 2 lookup T1

echo "4"
ip route add default via 192.168.21.2 dev eth1 table T1

echo "5"
ip route flush cache
____________________________________________________________________________

but the old FWMARK-problem:

debian:~# sh portroute

I search the problem until this time in kernel options, but I never find a
fwmark-option or modul.
I use Debian Woody or Debian on 2.4.26 Kernel.

Thanks very, very much, Holger
