Manual:IP/Cloud

Applies to RouterOS: v6.14+

Note: Currently running as public beta. Server availability could vary, and syntax could change

Summary

Starting with RouterOS v6.14 MikroTik offers a Dynamic DNS name service for RouterBOARD devices. This means that your device can automatically get a working domain name, this is useful if your IP address changes often, and you want to always know how to connect to your router.

Currently the cloud service only provides two services:

• ddns (provide dns name for router's external IPv4 address. IPv6 not supported)
• approximate time (accuracy of several seconds, depends on UDP packet latency, useful when NTP is not available)

Note: to actually connect to the router using the DNS name provided by cloud server, user must update router's firewall

Warning: Be aware that if router has multiple public IP addresses and/or multiple internet gateways, the exact IP used for the update may not be as expected!

Operation details

• Router checks for outgoing IP address change: every 1 minute
• Router waits for cloud server response: 15 seconds
• DDNS record TTL: 60 seconds
• Cloud time update: after router restart and during every ddns update (when router external IP address change or after force-ddns-update command);

After router sends it's IP address to the cloud server, it will stay on the server permanently. DNS name (/ip cloud dns-name) will resolve to last sent IP address even if user set /ip cloud enabled = no. Currently there is no way to remove/disable this DDNS record and there is no expire time for it.

Properties

Sub-menu: /ip cloud

Property	Description
enabled (yes | no)	If set to "yes" then router will send an encrypted message to the MikroTik cloud server. Server will then decrypt the message and verify that sender is an authentic Mikrotik router. If all is OK then server will create a DDNS record for this router and send response to the router. Every minute the cloud service on the router will check if external IP address matches the one sent to server and will send encrypted update to cloud server if IP address changes.
force-update (command)	When executed, ddns update to cloud server will be sent immediately, even if router's IP address is not changed. Note: if /ip cloud update-time is set to "auto" then router clock will be updated to cloud server time (if no ntp or sntp client is enabled). Cloud must be enabled to execute this command (/ip cloud enabled = yes)
update-time (yes | no)	If set to "yes" then router clock will be set to time, provided by cloud server IF there is no SNTP or NTP service enabled. If set to "no" then cloud service will never update router clock.
public-address (string)	Read only, shows router IPv4 address that was sent to cloud server and assigned to DNS name (see "/ip cloud dns-name"). This field is visible only after at least one ddns-request was successfully completed.
warning (string)	Read only, shows a warning message if IP address sent by router differs from IP address in UDP packet header as visible by cloud server. Typically this happens if router is behind NAT. Example: "DDNS server received request from IP 123.123.123.123 but your local IP was 192.168.88.23; DDNS service might not work"
dns-name (string)	Read only, shows DNS name assigned to the router. Name consists of 12 character serial number appended by .sn.mynetname.net. This field is visible only after at least one ddns-request is successfully completed.
status (status; Default: {{{default}}})	Read only, contains text string that describes current dns-service state. The messages are self explanatory updating... updated Error: no Internet connection Error: request timed out Error: REJECTED. Contact MikroTik support Error: internal error - should not happen. One possible cause is if router runs out of memory

Example

To enable and activate this service:

[admin@MikroTik] /ip cloud> set enabled=yes
[admin@MikroTik] /ip cloud> print 
         enabled: yes
     update-time: yes
          status: updated
        dns-name: 123456789abc.sn.mynetname.net
  public-address: 159.148.147.211
[admin@MikroTik] /ip cloud> 

Sub-menu: /ip cloud advanced

Property	Description
use-local-address (yes | no)	By default, the DNS name will be assigned to the detected public address (from the UDP packet header). If you wish to send your "local" or "internal" IP address, set this to "yes"
