DDNS.ORG MIkrotik configuration

{primary} To configure a Mikrotik router with DDNS.org service you should use the provided script and set a cron job that calls the script.

• Step 1

  Connect to the router using a Terminal (like puTTY) or Winbox software.

• Step 2

  Substitute in the following script your values for YOURUSERNAME, YOURPASSWORD, YOURHOSTNAME getting the values from your ddns.org account

# Set the following values from your ddns.org account https;//ddns.org/dashboard/configuration
    :local username "YOURUSERNAME"
    :local password "YOURPASSWORD"
    :local hostname "YOURHOSTNAME"

## no need to modify after this line.

    :global dyndnsForce
    :global previousIP

# print some debug info
    :log info ("UpdateDynDNS: username = $username")
    :log info ("UpdateDynDNS: password = $password")
    :log info ("UpdateDynDNS: hostname = $hostname")
    :log info ("UpdateDynDNS: previousIP = $previousIP")

# get the current IP address from the internet (in case of double-nat)
    /tool fetch mode=http address="checkip.dyndns.it" src-path="/" dst-path="/dyndns.checkip.html"
    :delay 1
    :local result [/file get dyndns.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 "UpdateDynDNS: currentIP = $currentIP"

# Remove the # on next line to force an update every single time - useful for debugging,
# but you could end up getting blacklisted by DynDNS!

#:set dyndnsForce true

# Determine if dyndns update is needed

    :if (($currentIP != $previousIP) || ($dyndnsForce = true)) do={
        :set dyndnsForce false
        :set previousIP $currentIP
        :log info "$currentIP or $previousIP"
        /tool fetch user=$username password=$password mode=http address="update.ddns.org" \
        src-path="nic/update?hostname=$hostname&myip=$currentIP" \
        dst-path="/dyndns.txt"
        :delay 1
        :local result [/file get dyndns.txt contents]
        :log info ("UpdateDynDNS: Dyndns update needed")
        :log info ("UpdateDynDNS: Dyndns Update Result: ".$result)
        :put ("Dyndns Update Result: ".$result)
    } else={
        :log info ("UpdateDynDNS: No dyndns update needed")
    }

If you use Winbox

Paste the script using the menu System->Script

If you use a Terminal

You should first create a new system script using the following commands:

/system script
add name=DDNS
policy=read,write,test

and then paste the script.

• Step 3

  Add a scheduler that calls the script every 5 minutes to send an update when IP changes.

/system scheduler add comment="Update DDNS" interval=5m name=ddns_sheduller \
on-event="/system script run DDNS\r\n" policy=read,write,test start-time=startup
