Port Forwarding from 80 to 8080 in Yosemite

_forward80.md

Add com.coverall file to /etc/pf.anchors with:

rdr pass on lo0 inet proto tcp from any to 127.0.0.1 port = 80 -> 127.0.0.1 port 8080
rdr pass on en0 inet proto tcp from any to any port 80 -> 127.0.0.1 port 8080
rdr pass on en1 inet proto tcp from any to any port 80 -> 127.0.0.1 port 8080
rdr pass on en2 inet proto tcp from any to any port 80 -> 127.0.0.1 port 8080

Update pf.conf to point to this new file a-la:

scrub-anchor "com.apple/*"
nat-anchor "com.apple/*"
rdr-anchor "com.apple/*"
rdr-anchor "coverall"
dummynet-anchor "com.apple/*"
anchor "com.apple/*"
load anchor "com.apple" from "/etc/pf.anchors/com.apple"
load anchor "coverall" from "/etc/pf.anchors/com.coverall"

Run: sudo pfctl -ef /etc/pf.conf

To startup port forwarding on boot:

cd /Library/LaunchDaemons

sudo curl -O https://gist.githubusercontent.com/eddanger/f67ce14f69c32bccfecc/raw/0c887ad24678241a6f1fb1855641bd63574fc80a/com.coverallcrew.firewall.plist
