ANSWERED External access to nextcloud: help me correctly forward my ports!

Recommended Posts

I have the VPN set up on my router. In the past I have successfully forwarded ports, using iptables, for a torrent client and a subsonic server that's running on a raspberry pi (my subsonic account uses a subdomain on subsonic.org).


Now I've installed nextcloud on another raspberry. I can access it locally via the raspberry's ip, but I can't get to it externally. For external access, I'm hoping to use a subdomain on my own website.


Here's what I've done:


1. Pointed the A Record of my subdomain (cloud.mysweetsite.com) to my DHCP ip address.

2. Forwarded a port on airvpn.com, using local port 443.

3. In my router (dd-wrt), I set up this iptable:


iptables -I FORWARD -i tun1 -p udp -d --dport 15119 -j ACCEPT
iptables -I FORWARD -i tun1 -p tcp -d --dport 15119 -j ACCEPT
iptables -t nat -I PREROUTING -i tun1 -p tcp --dport 15119 -j DNAT --to-destination
iptables -t nat -I PREROUTING -i tun1 -p udp --dport 15119 -j DNAT --to-destination

15119 is the port I forwarded on airvpn.


4. in /etc/apache2/sites-available/nextcloud.conf I'm specifying ServerName cloud.mysweetsite.com


What am I missing? What have I done wrong? Perhaps I should ask on the nextcloud forums instead of here! But it just seems like the vpn adds an extra layer...

I resolved this by simply specifying a different port in the apache settings.


Like, I changed it from 443 to the new one in:

Scratch that. Actually that didn't solve it. That allowed me to access the site via the domain name while on my own network. But once I'm outside my network, I can't get to it. Not sure what to do!


Right now I'm using the port that I forwarded on the airvpn site. It's not using local port 443.

Why did you point the A record to your DHCP address instead of the VPN server exit? This is incorrect.

What does the TCP test on the port check utility say?



It shows green. "Reachable on server IP over the external port..."


And at first I had the A Record pointed to the VPN server exit. But when doing so, the url did not resolve to the nextcloud server (however, this very well may have been due to incorrectly set up iptables). So I asked a friend, and he told me I was pointing it to the wrong address. Okay, I'll try to the VPN server exit. Thanks!
