I'm not going to claim to be an expert here, but my recent success makes me
think that using firewall marks might be easier/better.

Then you can define any grouping of ports/protocols (I believe?) inside of
that fwmark. I could be wrong though... since the configuration still has a
"protocol" line.

Someone more clued can shoot me down now :)
