Message after installing

Version 2 of dnscrypt-proxy is written in Go. by default, this port's daemon
will listen on port 5353 (TCP/UDP) as the _dnscrypt-proxy user.

It's possible to bind it and listen on port 53 (TCP/UDP) with mac_portacl(4)
kernel module (network port access control policy). For this add
dnscrypt_proxy_mac_portacl_enable=YES in your rc.conf. The dnscrypt-proxy
startup script will load mac_portacl and add a rule where _dnscrypt-proxy user will
be able to bind on port 53 (TCP/UDP). This port can be changed by
dnscrypt_proxy_mac_portacl_port variable in your rc.conf. You also need to
change dnscrypt-proxy config file to use port 53.

Below are a few examples on how to redirect local connections from port
5353 to 53.

[ipfw]

  ipfw nat 1 config if lo0 reset same_ports \
    redirect_port tcp 127.0.0.1:5353 53 \
    redirect_port udp 127.0.0.1:5353 53
  ipfw add nat 1 ip from any to 127.0.0.1 via lo0

  /etc/rc.conf:
    firewall_enable="YES"
    firewall_nat_enable="YES"

  /etc/sysctl.conf:
    net.inet.ip.fw.one_pass=0

[pf]

  set skip on lo0
  rdr pass on lo0 proto { tcp udp } from any to port 53 -> 127.0.0.1 port 5353

  /etc/rc.conf:
    pf_enable="YES"

[unbound]

  /etc/rc.conf:
    local_unbound_enable="YES"

  /var/unbound/unbound.conf:
    server:
      interface: 127.0.0.1
      do-not-query-localhost: no

  /var/unbound/forward.conf:
    forward-zone:
      name: "."
      forward-addr: 127.0.0.1@5353

  If you are using local_unbound, DNSSEC is enabled by default. You should
  comment the "auto-trust-anchor-file" line or change dnscrypt-proxy to use
  servers with DNSSEC support only.
