[Cake] Using cake on IMQ interfaces: when to use the "nat" option?

[Funshun Wang]

I have redirected upload traffic to imq0 by using IMQ in the PREROUTING chain and download traffic in the POSTROUTING chain to imq1. 




Upload traffic --> -i br-lan+tun --> imq0 


Download traffic --> -o br-lan+tun --> imq1 




IMQ module is set to before NAT in PREROUTING and after NAT in POSTROUTING. 




So on which interface should I enable the "nat" option, imq0, imq1, both or none? 




Thanks.
