I’m sure it is, but not on ports 80 or 443–at least not without major rework to the current web server package. Is there a particular reason you want it to be done with nginx rather than Apache?
Could you explain a bit more your request? Do you want a better Reverse Proxy support? Or do you need a running Nginx istance on NethServer? What else?
In my network I ozhidaetsya replenishment web servers (Apache, Ngix, IIS) with different domain names, do I need to do reverse proxy caching is desirable and with Let’s Encrypt ssl for all servers, that would be all cerificate was in one place and updated automatically. In this case Nginx is more flexible and faster, so the choice for frontend fell on it.
