Script API Mikrotik for Autoupdate Port Forwarding NAT by IP DDNS (revised)

Script untuk mikrotik Os6 dan Os5 menggunakan Provider dari DynDns.com

:global ddnsuser "username"
:global ddnspass "password"
:global theinterface "WAN"
:global ddnshost your-domain.dyndns.net
:global ipddns [:resolve $ddnshost];
:global ipfresh [ /ip address get [/ip address find interface=$theinterface ] address ]
:if ([ :typeof $ipfresh ] = nil ) do={
   :log info ("DynDNS: No ip address on $theinterface .")
} else={
   :for i from=( [:len $ipfresh] - 1) to=0 do={
      :if ( [:pick $ipfresh $i] = "/") do={
    :set ipfresh [:pick $ipfresh 0 $i];
      }
}

:if ($ipddns != $ipfresh) do={
    :log info ("DynDNS: IP-DynDNS = $ipddns")
    :log info ("DynDNS: IP-Fresh = $ipfresh")
   :log info "DynDNS: Update IP needed, Sending UPDATE...!"
   :global str "/nic/update\?hostname=$ddnshost&myip=$ipfresh&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG"
   /tool fetch address=members.dyndns.org src-path=$str mode=http user=$ddnsuser \
         password=$ddnspass dst-path=("/DynDNS.".$ddnshost)
    :delay 1
    :global str [/file find name="DynDNS.$ddnshost"];
    /file remove $str
    :global ipddns $ipfresh
  :log info "DynDNS: IP updated to $ipfresh!"

/ip firewall nat
# set ini maksudnya nomor di firewall nat yang akan di update dari angka 1 s/d terakhir , berhubung yang diupdate pada line ke 1,16.34,35
maka saya pasang (set) discriptnya
set 1 dst-address=$ipfresh
set 16 dst-address=$ipfresh
set 34 dst-address=$ipfresh
set 35 dst-address=$ipfresh

    } else={
     :log info "DynDNS: dont need changes";

/ip firewall nat
set 1 dst-address=$ipfresh
set 16 dst-address=$ipfresh
set 34 dst-address=$ipfresh
set 35 dst-address=$ipfresh
    }
}

dan beri nama dyndns --kemudian jalankan scriptnya ( run script)

=======================================================

Schedule
/system scheduler
add interval=1m name=DynDns on-event=DynDns policy=ftp,reboot,read,write,policy,test,winbox,password,sniff,sensitive,api start-time=startup

dan beri nama scheduleDyndns
