Mikrotik is so powerful but unfortunately it doesn't support dynamic DNS service without using a script...
I had to create a full new config before some days so i was searching for the DDNS option but couldn`t find a thing.
So after our dear friend google there seems to be a script to bypass this limit:
# Set needed variablesAfter we save the script, we have to add a new scheduled job in the event which we just made with an interval of.. let's say... 15 minutes?
:local username "yourusername"
:local password "yourpassword"
:local hostname "yourdyndnsorgname.dyndns.org"
:global systemname [/system identity get name]
:if ($systemname = "Site1" ) do= {
:set hostname "yourdomain1.dyndns.org"
}
:if ($systemname = "Site2" ) do= {
:set hostname "yourdomain2.dyndns.org"
}
:if ($systemname = "Site3" ) do= {
:set hostname "yourdomain3.dyndns.org"
}
: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.org" src-path="/" dst-path="/dyndns.checkip.html"
: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 "" -1]
:local currentIP [:pick $result $startLoc $endLoc]
:log info "UpdateDynDNS: currentIP = $currentIP"
# Remove the # on next line to force an update every single time - useful for debugging,
# but you could end up getting blacklisted by DynDNS!
#:set dyndnsForce true
# Determine if dyndns update is needed
# more dyndns updater request details available at http://www.dyndns.com/developers/specs/syntax.html
:if (($currentIP != $previousIP) || ($dyndnsForce = true)) do={
:set dyndnsForce false
:set previousIP $currentIP
/tool fetch user=$username password=$password mode=http address="members.dyndns.org" \
src-path="/nic/update?hostname=$hostname&myip=$currentIP" dst-path="/dyndns.txt"
:local result [/file get dyndns.txt contents]
:log info ("UpdateDynDNS: Dyndns update needed")
:log info ("UpdateDynDNS: Dyndns Update Result: ".$result)
:put ("Dyndns Update Result: ".$result)
} else={
:log info ("UpdateDynDNS: No dyndns update needed")
}
Now you can 'remote access' easily.
