Hello,
How do I access a Docker application from outside the network?
My Livebox (router) is working fine (I can access a Raspberry Pi from outside the network) (internal port 8080, external port 8788, TCP, NAS IP; internal access to this port is working fine)
Do I need to adjust the NAS firewall settings?
Thank you for your help...

Bonjour,
Comment puis-je accéder à une application Docker depuis l'extérieur du réseau ?
Ma Livebox (routeur) fonctionne correctement (je peux accéder à un Raspberry Pi depuis l'extérieur du réseau) (port interne 8080, port externe 8788, TCP, adresse IP du NAS ; l'accès interne à ce port fonctionne correctement)
Dois-je modifier les paramètres du pare-feu du NAS ?
Merci pour votre aide...

Which docker application do you mean?
Can you access it locally?

- Trilium : Local access OK (192.168.1.14:8788)
- Portainer : Local access OK (192.168.1.14:5443)

(I can access a Raspberry Pi from outside the network) (internal port 80 external port 8080, TCP, NAS IP; internal access to this port is working fine)
http://86.XXX.XXX.XX:8080 - ok)

It's recommended to configure your own DDNS per our instruction: https://toshelp.terra-master.com/docs/T ... ccess#ddns

Configure router port forwarding: You need to map the router's port to the NAS's internal IP address.

After setting this up, you can access Portainer or Trilium from anywhere with internet access using "your DDNS domain name:external port number".
