Is it possible to set up ddns for a computer on a home network through a router?

Question

linux

Good time!
Network topology of a standard home user -- the router is connected to an ISP without a dedicated ip, and my computer and devices are connected to it. My pc is running linux.
I would not want to configure ddns on the router. Is it possible to set up something similar on my computer, and on the router to do only port forwarding to my (permanent on the local network) ip?
Thank you all =)

Answer 1

Yes, of course, if your router receives a white address, and not some kind of 10.x.x.x
ok goolge:ddns linux

Answer 2

Can. ddclient configuration example:
cat /etc/ddclient.conf

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf

protocol=dyndns2
use=web, web=checkip.dyndns.com, web-skip='IP Address'
server=members.dyndns.org
login=
password=''

The key is the line
which indicates that ip must be taken from an external service, and not from the local interfaces of the computer.

Answer 3

You can set up DDNS on any device provided you get a white IP address.
If you want to set up DDNS on your computer, then for the local network you need to enable and configure distribution from a range of white IP addresses.
If you still decide to configure the router, then it must receive white IP addresses from the provider.
