Network Help Please?

I recently moved , after plugging in True nas would need to be reboot about once a week . So I thought oh hey I will reset my network and grab a new configuration. At the console ( not web ) I selected option 1 configure network interface and then selected the only one list and then dns and the rest defaults . This must have been a bad move , now my web interface is not working on the IP or smb .
Can this be fixed and how ?
Thanks for any help or direction ,
John

steps taken
Configure network interface
2a) Reset interface config? Y
2b) Configure DHCP? Y
2c) IPv4: entered
2d) IPv6: entered

after rest the ip didn’t change and I can no longer access gui which was working before this.

was testing it out for ya as i too had forgotten how to do it hahaha… Are you attempting to get an IP from your DHCP server? If not you need to turn off IPv4 and give it an Alias such as 192.168.1.200/24.

so like this ?
Configure network interface
2a) Reset interface config? Y
2b) Configure DHCP? Y
2c) IPv4: 192.168.1.200/24 ( or what it Keeps displaying as the gui IP )
2d) IPv6: entered

I think it should be like this.

Configure network interface
2a) Reset interface config? Y
2b) Configure DHCP? N
2c) IPv4: 192.168.1.200/24 ( or what it Keeps displaying as the gui IP )
2d) IPv6: entered

Are you using Scale or Core?

core If I recall…
Well now nothing worked after that ( I forgot to mention that Plex is still working but after I did that it all failed ).
So then I deleted the network interface and did this again
Configure network interface
2a) Reset interface config? Y
2b) Configure DHCP? Y
2c) IPv4: entered
2d) IPv6: entered
and now plex is working again but still no gui or smb
which is 192.168.1.# ( # just so I am not posting the actual )

also “Reset to factory defaults” I am assuming this would wipe it all like my shares , Plex and such ?

if you selected DHCP as Y, then an IP address will be automatically applied by your DHCP server/Router.

Maybe you could boot into shell and do an ifconfig to see what is the IP Address that has been assigned.

ifconfig list the net as the ip that is being displayed for the gui access which is also the correct network adapter ( I only have one ).
will the “Reset to factory defaults” just do configuration like these or all settings ( so then my smb and Plex will be dead ?)

I believe that wipes the database of all settings, essentially making the system behave like you just installed TrueNAS.

The pools aren’t wiped though, so any data there will remain.
I am not sure if it will import the pools automatically after rebooting, but I suspect not.

You will need redo your network configuration, shares, users, apps and so on.
I wouldn’t recommend it in your situation, at least not yet.

Don’t sett DHCP to Y and enter an IPv4 alias. Do one or the other. A NAS is something you typically want to always be available on a specific IP so my recommendation is to disable the dynamic allocation (DHCP) and just set the IP-address you want your TrueNAS system to have. Ideally something not inside the DHCP range used by your router as to avoid a collision some time in the future.

I did a
ifconfig <interface_name> down
ifconfig <interface_name> up
but a reboot does that .
Then I did a
dhclient <interface_name> -4 -N
which seemeds to have fixed the issue
I am back thanks everyone
