Pf on lo0

[Luke Small]

I'm trying to have pf limit sending TCP packets over lo0 from a specific
user. I made some rules, but they seem to be ignored when I check on pfctl
-vvvs rules it goes to the default lo0 pass rule: "pass out quick on lo0
proto { tcp, udp } from self port 6379 to any port 6379 user luke" and
"block out quick on lo0 proto {tcp,udp} from self to any port 6379"
obviously I'm using redis. Redis has authentication, but I think it'd be
cool to have that extra layer of protection.
