Strange forwarding issue (Gateway and interVLAN)

Hi,

version 24.1.4
Using UnboundDNS

I have 3x VLANs.
On one of them I have a Google TV device.

All working fine, but for some reason every so often OPNSense seems to stop this device from crossing the gateway, and it cannot exit to Internet nor reach other VLANs.
but strangely the device is active and reachable from the same VLAN.
If I restart the networking or reboot the Google TV, it connects to Internet again but again after 15-20 minutes the same behaviour happens again.
I can't find much logs to understand what happens and would appreciate some direction where to look!
thanks

Hi,

do you have suricata, zenarmor or anything similar enabled?

Please also check on firewall live log whether there is any blocked traffic coming from your google device. Also, once failing, check the IPv6 address configuration of the google device. Does it still have a GUA?

And last but not least check the IPv4 leases on DHCP for that devices. Are they renewed on time or are they inactive after you lose interne?

No, none of those....

In the log I can't find any blocked traffic unfortunately, it seems all of a sudden the firewall stops forwarding:

-InterVLAN
-From VLAN outward to the Internet

On the Google TV (Nvidia Shield) I have disabled at all IPv6 and I also set IP address to static while troubleshooting for any possible DHCP issue.

But I have a feeling now it's all the devices having issues but I noticed only this one for now.

What seems to make it work again is to apply any saving in on the Interface page of OPNsense and apply.
Like if it was flushing or restarting something.

Forgot to mention OPNSense is running in a ESXi VM....

Hi,

that's odd behaviour. Routing stops while the webgui is still alive - what about the VMs configuration in terms of hardware (drivers), software, offloading and is there any clue in the system's backend log?
