Shorewall users - Mar 2006 - Multi ISP + traffic shaping

If I understand correct in a Multi ISP env  traffic shaping affects indirectly
loc->net   routing if the packet is marked.

Correct ?? Or I missed some documetation.

To use Multi-ISP with traffic shaping, the traffic shaping marking:

a) Use classifiers for traffic shaping rather than firewall marks (see the 
documentation at the top of /etc/shorewall/tcrules -- With the built-in 
traffic shaper, the major class is the interface number (order in tcdevices) 
and the minor class is 100+the class mark).

Here''s an example using my files:

/etc/shorewall/tcdevices:

#INTERFACE      IN-BANDWITH     OUT-BANDWIDTH
$EXT_IF         1.3mbit         330kbit
#LAST LINE -- ADD YOUR ENTRIES BEFORE THIS ONE -- DO NOT REMOVE

/etc/shorewall/tcclasses:

#INTERFACE  MARK    RATE            CEIL            PRIORITY        OPTIONS
$EXT_IF     10      full            full            1               
tcp-ack,tos-minimize-delay
$EXT_IF     20      9*full/10       9*full/10       2               default
$EXT_IF     30      6*full/10       6*full/10       3
#LAST LINE -- ADD YOUR ENTRIES BEFORE THIS ONE -- DO NOT REMOVE

/etc/shorewall/tcrules:

#MARK   SOURCE          DEST            PROTO   PORT(S) CLIENT  USER    TEST
#                                                       PORT(S)
1:110   192.168.0.0/22  $EXT_IF        #Our internel nets get priority
                                       #over the server
1:130   206.124.146.177 $EXT_IF         tcp     -       873
#LAST LINE -- ADD YOUR ENTRIES BEFORE THIS ONE -- DO NOT REMOVE

b)  Apply your routing marks in the PREROUTING chain and your traffic-control 
marks in the FORWARD chain.
