Hi,

I am not sure, but you are probably missing the extra module from
patch-o-matic-ng...

Subject: iptables + ROUTE 

Hi, 

I am new in iptables world - and after reading many discussions and studying
iptables manpages etc. I am 
still missing a piece of puzzle to solve the following problem. 
I have a need to perform TOS based traffic routing. 
That means I have two interfaces (say eth0 and eth1) to backbone and I need
to route the real-time critical 
IP traffic over eth1 and the remaining IP traffic over eth0. 
After a lot of experimenting I came to the conclusion that something like
the following would do: 

# iptables -t mangle -A POSTROUTING -m tos --tos  16 -j ROUTE --oif eth1 
# iptables -t mangle -A POSTROUTING -m tos --tos !16 -j ROUTE --oif eth0 

Unfortunately the Linux box says: 
"No chain/target/match by that name" 

The kernel I use is 2.6.18, iptables version is the last debian stable
version 1.2.11. 

Any idea what is wrong here (am I missing something in the configuration, or
a library, or am I completely wrong maybe.)?

Thanks for any help. 

Br. 
Mato
