Basic authpf setup (cont)

Let users authenticate

pass quick on $int_if inet proto { tcp, udp } to $int_if port ssh

Other rules could just as easily go in authpf.rules

pass quick inet proto { tcp, udp } from <authpf_users> to \
     any port $udp_services
pass inet proto tcp from <authpf_users> to any port $client_out
