I am trying to forward all ports except port 22 on OSX Sierra using pfctl but it doesn't seem to work.
ext_if = "inet" rdr pass $ext_if proto tcp from any to any -> 127.0.0.1 port 12345 rdr pass $ext_if proto udp from any to any -> 127.0.0.1 port 10053 pass out proto tcp from any to any port ssh
I enabled it with
sudo sysctl -w net.inet.ip.forwarding=1 sudo pfctl -f pf.conf sudo pfctl -e
The traffic seems to be redirecting fine to port 12345, but I can't get port 22 to passthrough.
