To the router
Hardware Version:
ER605 v2.0
Firmware Version:
2.0.0 Build 20220106 Rel.56391
A PC with Ubuntu 20.24 on board is connected by wire through an unmanaged switch.
The PC is statically assigned an IP and the same IP is reserved for the mac address of this PC on the router side.
Nextcloud is installed and launched on the PC via snap.
The router forwards ports 80 and 443 to the local IP of this PC.
Our external IP is static, dedicated, white, specially rented from the provider.
If we go to a domain that is tied to our external IP, everything works as it should.
But, being on the local network, it is not possible to visit our cloud not by domain or by external IP.
Only by passing through the local IP of our server.
Interestingly, nextcloud previously worked on Windows 10 via Docker with the same router, with the same settings, and everything worked as it should.
It’s also interesting that on the local network the cloud comes off from under the VPN (for example, cloudflare 1.1.1.1).
Do I understand correctly that the problem here can only be in the router?
Or what other options might there be?
