I'm running OS X 10.10 and with a local proxy running on port 7777. I've been searching high and low for the best way to redirect all my local traffic to this proxy but haven't come up with much. As of now I believe the best option is to use `pf` (or possibly iptables in previous versions of OS X). Would this be the most logical solution? If so, how would I go about implementing it with `pf`?
