I'm not sure there is much point in separating NFS from other traffic, 
since they typically travel in opposite directions. For example a file 
download will involve packets coming into a client from the router and 
back out to the  NFS server. Your NICs are full-duplex so the two types 
of traffic shouldn't get in each-others way very much.
