Thank you for answering,
I don't want to connect to an external provider
I have my no-ip.com domain and I am connected to my Fai via a Huawei 4G LTE box
I want to connect to my home router when I travel in order to access the internet (this is not currently working)
I live in Martinique and I want my children who live in mainland France to be able to connect to my local network in order to have access to my data (under study because I have not yet succeeded in connecting my hard drives to the router, but this is not the subject of the current topic).
I attach my configuration or I installed wireguard server (this configuration has been saved because it is not active at the moment). Eventually I can restore it if you wish.
It is a configuration that I test before the arrival of version 20.xx (because the wiki has been modified). If you help me solve this problem, I will just have to integrate it into my working configuration.
It does not reflect my working configuration which is more secure and includes among others (Public key authentication, dnscrypt-proxy2 from the LuCi 2.0.44-1 package, etc.).
Thank you for your availability
