How to config the ddclient to make my pc which is in NAT accessible from a pc in the internet?

share|improve this question

Ddclient can be configured by running

sudo dpkg-reconfigure ddclient

in a terminal. This will create a /etc/ddclient.conf file that can be further edited to meet your needs, e.g.for the service you use for IP detection.

To make your lokal client accessible remotely you need to forward ports for the given remote services to your local client. You may also need to configure PAT or NPAT if many clients share a public IP.

If you don't have access to your router you can try to setup a SSH tunnel on existing open ports (see here and there). To have remote desktop access you may also consider Team Viewer or alternatives.
