NethServer Version: 7.6
Experience: Nethserver - Noob, Linux - experienced Beginner
Let’s start this off by saying that I have extensively googled this question.
I have recently installed nethserver on a small testing machine that is connected to the internet through a firewall that I’ve configured to portforward 80, 443 and 980. My domain and its subdomains all point to the external IP.
When I try to connect to its internal IP using another device, it works fine. I can access nextcloud through https://myinternalip/nextcloud, SOGo same, and Nethserver by Internal IP and Port.
But, when I try to connect from the outside using either domain or the external IP, SOGo and nextcloud fail on timeout.(Nethserver works fine on https://domain.tld:980/)
Now my question is: through what ports are the modules default? Or do they all get channeled through for 443? In that case, why can’t I access them? And where is that behaviour configured?(Because I also want to run a website off of it when I get this running…).
Sorry for spelling/grammar errors (english is not my native language)
TL;DR: Port forward, Modules from inside work, outside not. Why?
