Help with Reverse proxy

NethServer release 7.5.1804

Hi guys
I have the following configuration:

a) domain:
internal router

b) Router redirects services to a PC with Windows server DNS port 53 + IIS at internal address port 80

c) Vmware workstation with NAT network machine with NethServer with IP named with fowarding port so that the virtual machine services also respond to

Although I can receive and send emails with Thunderbird, web services:

  • Roundcube email
  • Nextcloud
  • Mattermost
    of NethServer can not access them with the external IP from the outside at port 443,5432 or even 80 if I stop IIS.

Is it possible to resolve with a certain configuration of NethServer Gateway / firewall or port forwarding? or is it apache setup (error log :Cannot serve directory /var/www/html/: No matching DirectoryIndex (index.html,index.php) found, and server-generated directory index forbidden by Options directive)?

Where and why do you use reverse proxy? On your router? In this case port forwarding should be enough.

Could you try it in brigde mode and assign an IP like to Nethserver and route the services (ports 80, 443) from your router to the new IP? IIRC these virtual NAT adapters make problems sometimes.

For mattermost you need a virtual host, roundcube or nextcloud should just work:
