yesterday, i have bougth a domain for my site: www.360mbx.com, and i want to use some subnetwork domains, such as:
mail.360mbx.com -- use my computer network port: 3000
gitlab.360mbx.com -- use my computer network port: 3001
api..360mbx.com -- use my computer network port: 3002

and this day, i download the dnclient tools, and but i dont know, how and where to set the ports binding for those subnetwork domains.

I just wonder know if your ddns just support the www.360mbx.com with port 80 for http or 443 for https?

Because if DYNU can match my request, I will buy the ssl certf and mail support, or I will stop my try.

Thanks,

You can use our port forwarding function in the 'Web Redirect' section in the control panel. For more information, you may refer to this tutorial at https://www.dynu.com/Resources/Tutorials/DynamicDNS/Advancedfeatures/WebRedirect.

Please make sure that you open the ports 3000, 3001 and 3002 in your router and firewall as well.
