Not necesarily.
Even if you pass the packet in nat table, you still might drop it in 
filter table. I know the ACCEPT target may be used in every (?) table, 
but it's a matter of good practice to filter packets in filter tables 
and nat in nat tables and so on. So I would suggest moving this from nat 
table to filter table and from PREROUTING to FORWARD.
