If you have Mikrotik Server with DSL connection with dynamic ip , which changes on every reboot / reset, and you want to access mikrotik from the Internet then you can use changeip.com (DynamicDNS) service, using this service, you don’t have to query the DSL IP every time, all you have to remember the domain name that you register on the site, and rest of things will be handled by the DDNS script configured on the Mikrotik.
Following is the the scenario:
INTERNET => DSL MODEM => MIKROTIK
User with WINBox = (with dynamic ip)
DSL MODE IP = 192.168.30.1 (Device or Router opening IP)
MIKROTIK WAN IP = 192.168.30.5 (winbox Connect to )
CONFIGURE DSL MODEM TO ENABLE PORT FORWARDING
First open you
DSL Modem page to enable
PORT Forwarding (from DSL Modem to Mikrotik box)
Now
add Port Forwarding rule
WINBOX uses
TCP Port
8291
