for security reasons I only want to allow my Nextcloud-server to talk to ip-addresses and urls which it has to. So my firewall rule is like this:
Destination: URLs for Linux-Updates, NTP-Server, SMTP-Server …
(separated into several rules depending on the needed service, of course)
Now I am looking for a list of ip-addresses and urls that are needed by the nextcloud-server to work porperly. I found out that the nextcloud-Server needs the following:
- nextcloud.com:443 --> to check for updates
- 184.108.40.206:443 --> to check for apps (the ip belongs to reverseproxy.nextcloud.com which can not be resolved)
github.com:443 --> to download new apps
These are the urls/ips which I found yet, but I guess there are some more, that are needed to have the full comfort of nextcloud. Does anyone knows where to get this list?
