edit /usr/local/etc/mpd5/mpd.secret

abcd 123456   //account password

edit /etc/rc.conf

gateway_enable="YES"

pf_enable="YES"
pf_rules="/etc/pf.conf"
pflog_enable="YES"
pflog_logfile="/var/log/pflog"

mpd_flags="-b"
mpd_enable="YES"

edit /etc/pf.conf

ext_if ="hn0"

table persist {10.10.1.0/24}

nat on $ext_if from to any -> ($ext_if)
pass in all
pass out all
#pass in quick inet from to any keep state

重新啟動之後，使用abcd及密碼123456撥接登入vpn server
