Truenas IP shows up on router but cannot ping or connect to GUI

TrueNAS General
1

As far as I can tell my Laptop is (or appears to be) on the same subnet as Truenas. just stating that up front.

My server motherboard has two gigabit ports (eno 1 & eno 2) and two SFP+ ports (eno 7, eno 8). I recently tried getting a 10G connection up and running a few weeks ago and am afraid I upset whatever connectivity settings made things work.

This might not be relevant but for completeness:

  1. I previously has truenas connecting to my homenetwork via gigabit on eno 1
  2. I tried having SFP+ and gigabit work together but that never seemed to work
  3. I think I disabled eno 1 (or turned off DHCP) and I was connected via SFP+ for a week or two
  4. I tried going back to connecting via eno 1 and it doesn’t work.
  5. I futzed around and now cannot connect to the SFP+ port either.

I have been stumped trying to get this to work. I have simplified my setup to the following pic: my router connects to a gigabit swtich, and I have my laptop and NAS both plugged into the switch. Same subnet and everything.

my router can see that truenas is connected at the IP truenas says it’s hosting the GUI

-------- The info you probably really care about ------

I have connected a monitor to my server and updated the network configs to the following

  • eno 1 DHCP is on. → gets assigned 192.168.0.xxx
  • one SFP+ port (eno 7) is manually set to a different static IP on 192.168.0.2xx (this port is not connected for this test)
  • rebooting TrueNAS ends on the screen indicating that the GUI is being hosted at these two IP addresses
  • My home router sees the eno 1 IP
  • I cannot ping this IP
  • I cannot connect to it from a browser on my laptop (tried different browsers, tried via physical connection or over wifi)

I’m at a loss. I’m hoping one of you kind souls can walk me through troubleshooting. Or maybe I should just reset the network config to defaults and hope for the best?

Thank you!

Screenshot from a Core system
bge0 is a 1Gbps
ix1 is a Intel x520 with SFP+ fiber

This is how I have mine set. Windows box has two NICs also. Fiber gets a static IP on both. 1Gbps NICs on both use DHCP.

I have 1Gbps NICs connected to router that gives out DHCP. Fiber is a direct fiber connection between TrueNAS and Windows. No switch

You can’t have both your NICs on the same subnet as you show.

Thanks, let me give this a try

:scream: ahhhh it works!

I am embarrassed at how simple a fix this was. I didn’t think it would cause a problem to assign two NICs to the same subnet on a single machine…especially if one isn’t even connected.

I don’t fully understand why this is an issue but thank you getting me back on the right path!
