Simply enable a mikrotik router remote access with your own domain by DDNS
1, Go to ip/cloud and enable the DDNS builtin service. you will see a your routers
sn number+sn.mynetname.net shows up. that's your ddns address, but it is hard to remember..
2, Login to your domain dns manager and add a CNAME record pointing to the ddns address generated in mikrotik.
3, Change the www/winbox default port (especially for www port because your ISP provider should block 80 and 443)
4, Open browser and type http:// yourdomain:xxxx and check Winbox also.
