internet gateway (NVG599) rebooting after starting new VM from Gui 11u2

[M@TT]

So not even sure what to start looking at for possible cause here. I finally took the plunge and upgraded from 9.10 to 11 and took a stab at creating a VM from the GUI vs from the command line like I have previously done.

Immediately after starting the VM I just created (server 2016 iso attached) I loose connectivity to my gateway and effectively have no network connection. If I try to ping my gateway I get super high response times and eventually I can see my wireless drop as my gateway reboots over and over and over.

So the first time this happened I thought surely what just happened had nothing to do with starting a VM in freenas and I proceeded to troubleshoot my gateway device for a couple hours going through resets and config changes until I gave up (this was painful as I had a small window and a large lag in working in the web interface) and unplugged my freenas from the rest of the network . After doing so and the device rebooted a final time I was able to get normal response times pinging my gateway and everything returned to normal. Plugged my freenas box in and was able to log in... seeing that the VM was not started I kicked it off to start again and boom! Same thing!

Needless to say I have replicated the issue multiple times and will be digging through the manual to see if I missed something in the upgrade path... but this is just weird.

If anyone has experienced something like this or knows what logs I can dig into to help track this down let me know.

I have not had that problem. I do have a couple of things to check though. Any chance your gateway and virtual machine have the same MAC address? It is randomly created, if it duplicates the gateway or any other computer on your network you will have issues. Also duplicate IP address causes issues. And then there is an issues if a machine has more than one gateway, this can cause some wild problems.

ok so I did check some of the usual suspects like duplicate IP's and definitely was concerned that somehow something else was grabbing my default gateway ip when the VM was kicked on but this does not seem to be the case. Did a scan of the network and verified no overlap seen and grab a fresh audit of mac addresses already talking.

Something else that I have noted so far as I dig into this is that after trying to start the VM and getting kicked out of the webpage for freenas (due to losing my GW device) once I am logged back in all of my encrypted drives are locked. A bit odd so will need to look into this as the system uptime doesn't change meaning no reboot of the system is happening.

Additionally I have 2 nics on my freenas box which are both plugged in. One is set with a static ip and the second is set to dhcp and was assigned to the iohyve network bridge. I suspect this is where I might find something miss-configured as freenas does not let you assign a second static ip to an interface that is in the same subnet.

will update as I continue to research the issue.

confirmed.... freenas rebooting when this is happening.
also created vlan and assigned second network connection to this device and set this to its own vlan on the switch its plugged into and was able to boot the vm without issue.
As soon as I attempted to delete the vlan interface while the vm was running the same issue came up... both freenas box and modem reboot.
I am going to have to get a wireshark of this now and see what is going on.
