Eccolo:

# No-IP automatic Dynamic DNS update Behind Nat By Frank

#————— Change Values in this section to match your setup ——————

# No-IP User account info
:local noipuser “noip_user”
:local noippass “noip_password”

# Set the hostname or label of network to be updated.
# Hostnames with spaces are unsupported. Replace the value in the quotations below with your host names.
# To specify multiple hosts, separate them with commas.
:local noiphost “noip_domain”

#————————————————————————————

:global previousIP

# get the current IP address from the internet (in case of double-nat)
/tool fetch mode=http address=”checkip.dyndns.org” src-path=”/” dst-path=”/nat.checkip.html”
:local result [/file get nat.checkip.html contents]

# parse the current IP result
:local resultLen [:len $result] :local startLoc [:find $result ": " -1] :set startLoc ($startLoc + 2)
:local endLoc [:find $result "</body>" -1] :local currentIP [:pick $result $startLoc $endLoc] :log info “UpdateNatNoipDNS: currentIP = $currentIP”

# The update URL. Note the “3F” is hex for question mark (?). Required since ? is a special character in commands.
:local url “http://dynupdate.no-ip.com/nic/update3Fmyip=$currentIP”
:local noiphostarray
:set noiphostarray [:toarray $noiphost] :foreach host in=$noiphostarray do={
:log info “No-IP: Sending update for $host”
/tool fetch url=($url . “&hostname=$host”) user=$noipuser password=$noippass mode=http dst-path=(“no-ip_ddns_update-” . $host . “.txt”)
:log info “No-IP: Host $host updated on No-IP with IP $currentIP”
}

Di seguito la solita schedulazione:

/system scheduler

add disabled=no interval=5m name=no-ip_ddns_update on-event=no-ip_ddns_update policy=ftp,read,write,test,winbox,api start-date=apr/21/2013 start-time=18:46:4

}
} else={
:log info “No-IP: Previous IP $previousIP is equal to current IP, no update needed”
}
} else={
:log info “No-IP: $inetinterface is not currently running, so therefore will not update.”
}

Poi ovviamente lo scheduliamo:

/system scheduler

add disabled=no interval=5m name=no-ip_ddns_update on-event=no-ip_ddns_update policy=ftp,read,write,test,winbox,api start-date=apr/21/2013 start-time=18:46:4
