Keeping TrueNAS LAN live through internet/router issues

TrueNAS General
1

Whenever I have generic internet connectivity issues (i.e. can’t connect to any website) I am always slightly surprised/disappointed that my TrueNAS server also loses connectivity and I can’t use the webUI/any services (e.g. syncthing UI).

Since my TrueNAS is completely on LAN, I feel it should be possible to have a more resiliant set up that allows me to continue using TrueNAS on LAN even if I can’t access the internet. I would like my local network to be completely independent of the internet.

Is something like this possible? I’m not a network engineer so I can’t gauge the feasibility. If there are any resources I could look into for this that would be appreciated.

Except for updates, alerts, remote access via VPN, and certain apps, TrueNAS does not require internet connectivity. It’s designed as a local network appliance.

What devices are on your network? Do you have a combo router/modem that some ISPs lease to their customers?

TN does not need an Internet connection to work.

Apps/catalog updates and TN updates would fail of course, but you can still access the GUI, ssh, SMB, etc.

It would help if you give better details, errors and explain “CAN’T use GUI/services”.
(hands tied suddenly?).

I will keep this in mind the next time it happens.

I do recall losing access to truenas when I last lost my internet connection but I haven’t experienced it recently.

Regarding devices just standard things like phones and laptops. About the router/modem I’ll have to look into that and try to find out. Thanks
