Unraid can't ping router, but VMs can

[cyberspectre]

I think something is misconfigured on my server. I can access the Unraid web GUI just fine from any device on my network. And both of my VMs connect to the internet without issue. But the server itself can't connect to the internet or even ping my router. 

 

I'm not sure when this happened, because it was working after I updated to 6.6.3. All I've done since then is set up an ethernet bridge between the two NICs so that I could connect a second computer to the network via the server's spare port. But if that is the cause, turning off the bridge and turning on bonding again does not fix it. In fact, when I do that, I can no longer access the server from any device except for the one plugged into the spare port, and it still can't ping the router.

 

I've attached my syslog and a screenshot of my network settings. Any thoughts?

 

Thanks!

Start with using private address space (10.x.x.x or 172.16.x.x or 192.168.x.x) for your local network. Address space 20.x.x.x is public (assigned to Microsoft).

Thanks, I didn't know that. I renumbered my network, but the problem persists. It seems that wasn't the source of the issue.

Maybe if I manually update the files on my usb device to unraid 6.6.6, that will fix it? Are there dangers associated with this?

Here is the output of diagnostics. Is there any more information I can provide that would help someone assist me?

What ip are you trying to ping? what ip are your vms?

My unraid UI isn't able to connect to the internet to update, get community apps, etc. I'm trying to fix that, starting with pinging my router.

 

My router is 172.16.1.1

My server is 172.16.1.2 (also tried 172.16.1.18 in case the router was reserving the first IP in the DHCP pool, but it isn't)

VM 1 is 172.16.1.3

VM 2 is 172.16.1.4

You've got bridging and vlans running of which I know squat about (except how to spell them), so no advice from my end

Well, I appreciate the effort to help anyway! 

 

I set up the bridge by following instructions given to me in this thread. But I didn't purposely create a vlan, nor do I know anything about them. I suspected the bridge might have something to do with the problem, but when I return the network settings to default, the problem still exists.

Not an expert by any means. But if you did not purposely create a VLAN, I would try to set VLAN to disabled on that screen and see if it will connect then.

Thanks for the help, everyone. I finally fixed it. All I needed to do was change the IP assignment from static to automatic in network settings. The address is the same either way because the MAC is bound to the IP by the router. Still, it only works when Unraid is set to get the address from DHCP.
