udp download(not upload) through second gateway...

Is possible to route udp download using second gateway(using mangle) but just download not upload…

This are my rules, but they work for up and down..:

 
chain=prerouting action=mark-routing new-routing-mark=link2 passthrough=yes 
     protocol=udp src-address-list=in2 port=1000-65454

also it looks like, that it marks also ports under 1000(udp) despite I want mark just above 1000…why?

in ip-route is marked second gateway as link2
