Traffic shapping Question

Hi

If I have

add chain=forward comment=“Allow Established connections” connection-state=established,related action=fasttrack-connection disabled=no
add chain=forward comment=“Allow Established connections” connection-state=established,related


as my first lines in forward, how does this affect my ability to traffic shape, will fasttrack by pass queue if I apply to interface.

Just to expand to this been doing some reading up.

I want to use marks. so in the mangle table I am looking at doing something like

prerouting

add chain=qos-prer src-address=a.b.c.d/32 action=mark-connection connection-state=new new-connection-mark=rlc_prod
add chain=qos-prer dst-address=a.b.c.d/32 action=mark-connection connection-state=new new-connection-mark=rlc_prod

then in forward

add chain=qos-pref connection-mark=rlc_prod action=mark-packet new-packet-mark=rlp_prod


I have 2 lines for prerouting as its asym routing and the key point is a.b.c.d is the same address for above.

notice I also use different names for connection marking and for packet marking - do I have to ? it makes it clearer for me to understand

is this the right approach

and do I have to now turn off fasttrack ..
