Setting up tailscale for external access

Instructions

First, you need to log in via SSH:

ssh USERNAME@IP

When asked for a password, use your account password.

Next, download and install tailscale as described here with this command:

curl -fsSL https://tailscale.com/install.sh | sh

Finally, start tailscale with

sudo tailscale up

After starting tailscale, I noticed that the NAS could not access any resources on the internet due to a broken DNS configuration. The cause for this issue is that UGOS uses the file /etc/resolv.conf to store the default nameserver but tailscale overrides it when launching.

To fix it, I had to restart tailscale with disabled DNS configuration

sudo tailscale down
sudo tailscale up --accept-dns=false
