Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version : 13.0.1
Operating system and version: Ubuntu 16.04
Apache or nginx version: Apache 2.4.25
PHP version : PHP 7.0

The issue you are facing:
I have an a nextcloud server running internally in my corporate network. I have both ports 443 and 80 open. I have included the DMZ IP address and External Public IP address in my nextcloud.conf file. My interfaces file has a second nic (eth1) that is static with the DMZ IP. My internet provider is setup with an A record to my alias with external public IP. Internally, I have a dns entry and static IP for server.

I can access the server internally but I get a “Directory Listing Denied: This virtual directory does not allow contents to be listed” when I try to access the server from external network. I disabled SSL temporarily to troubleshoot the problem.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. log into my hotspot (outside of my corporate network) and unable to access site (error: Directory Listing Denied)
  2. tried 3 different browsers
  3. tried in ubuntu and windows

Not sure if you solved it already, because when I open the URL, I can actually see the login screen (only via https). Via http, it says that I try to speak http while it expects https. So you perhaps forwarded the http-port to https. In your overwrite-config, you should also set https protocol.

If you still see this problem, then it’s probably from inside your network. Try with a smartphone or TOR browser to see how it looks from outside.

RESOLVED. Only took 2 months
I had to remove the default gateway entry for eth0 (my internal network) and add:
post-up ip route add x.x.x.x/24 dev eth0 src x.x.x.x table rt2
post-up ip route add default via x.x.x.x dev eth0 table rt2
post-up ip rule add from x.x.x.x/32 table rt2
post-up ip rule add to x.x.x.x/32 table rt2

and to eth1 (dmz network)

up route add -net 192.168.1.0 netmask 255.255.255.0 gw x.x.x.x

I followed this article here: https://www.thomas-krenn.com/en/wiki/Two_Default_Gateways_on_One_System#Initial_Position
The trick was having the default gateway defined for my external nic in interfaces file (not my internal nic).
