System problem on Application (Settings --> Advanced Settings)

Description

Before I change something in the "Settings" dropdown (on the left of Launch Docker Image button), I saved my truenas config, then I've changed the settings as follows: node ip from 0.0.0.0 to my node ip ehternet interface to the physical interface then save.

After that nothing is working:

  • I can not access to the webui

  • I can not ssh to my user

Then I successfully restored it by putting the monitor cable into my physical server and hard reboot it, then from the shell I've entered the config settings of kubernetes, and it gave me back the local ip to login, then I've restored the settings.

This is the origianl settings:

This is the one that broke it:

Hi Waqar,

 

Ok, I put the settings like the following, and I could reach TrueNAS Scale through the dns,

 

 

 

Thank you,

 i am not sure why would/should that work ? K8s traffic will be routed to your scale node ip and then do you have another routing rule for routing it from there to some other place ? I am still confused why you need to do that at all if at the end you want to use 192.168.1.1 as the gateway

Hi Waqar,

 

This node ip (192.168.1.50) is connected to the router as it's own gateway (192.168.1.1), and I thought that the apps from k8s, if they are using the node ip, it can use it also as a gateway. In this situation the node will route the traffic to the outside because it has the default gateway is set on 192.168.1.1

 is your SCALE node ip the default gateway ? I am not sure i follow the motivation behind setting it as the gateway ?

Hi Waqar,

192.168.1.50 is my TrueNAS Scale node IP.

 

After I changed it again as in the second screenshot (with node ip: 192.168.1.50),

  • I can reach through my local ip (home router)

  • I can not reach through dns

Also I attached the following scrrenshot from Alerts (when I've changed the settings as in the second screenshot with node ip: 192.168.1.50)

 

I attached the save debug in private section (after I returned the settings to original as in the first screenshot with node ip: 0.0.0.0) and now I can again reach TrueNAS through my dns again,

 

Thanks,

Arkan
