DDNS for OpenVPN

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi,

I am using this script for openvpn
https://openwrt.org/docs/guide-user/services/vpn/openvpn/server

Is it possible to modify to retrieve a DDNS such as something.ddns.net if I has a ddns through afraid.org? If so how would I modify the script?

Thanks,

Aaron

  • Are you saying that you want the DDNS to make a DNS record for your VPN IP instead of you WAN IP?
  • Or you wish to alter your config to use a different DDNS company?

It's not clear why you mentioned a VPN and 2 DDNS companies.

I have my ddns through afraid.org in the form of something.ddns.com and I was wonder how I would modify the script to detect if something.ddns.com was set and use that if not use the one of the other methods.

This is how I have modified the script! The rest of it I have left the same.
