Fixed my issue also. I stumbled on this earlier today and I came here to post the update. All the interfaces I had selected were automatically also selected for "no DHCP" option and hidden in the advance toggle switch. Once I deselected all of them, my leases started working.

I have the exact same issue. dnsmasq does not create firewall rules for chosen interfaces. Adding them manually doesn't seem to work and I can find any error messages generated in the logs. Adding floating rules doesn't seem to work either. With firewall rules in place I can see the port 67 and 68 traffic being passed, but no leases are ever negotiated. I gave up after trying a few times. I'll wait until a future update until it's more fully baked.

Have you tried using a monitor IP on the gateway? If you set a gateway to "monitor" the IP of the opposite gateway, does it still do this?

this kernel worked for me. I am using FQ_PIE without losing internet.

I'm seeing the same issue. I kept losing WAN on upgrade and could not figure out why. I tried three times. It was a Reddit user that clued me into the "PIE" issue and this post. Thanks for all your work on this. I'm hoping to give this a try as soon as I can.

Hello.

For clarity, I had this same issue on two different machines before testing the new Kernel. This issue only appears when Netmap ZA is in Routed Mode. In bypass or passive mode I have no issue.

The issue is specifically a router crash. Router becomes unresponsive and all connectivity fails for a period of time. Often requires a power reset to recover. 

The issue only appears when ZA is in routed mode and it only happens when transferring a single large file between vlans. Something like a 5GB .iso file. I can transfer a 5GB folder full of smaller files with no issue.

I have tried with the vlans on the same parent interface and I've also tried with the vlans on different physical interfaces. Same issue.

I'm currently using a Netgate 6100 with the 10G (ix) uplinks. I also had the same issue on my previous Dell SFF PC using X550-T2 NIC (also ix).

It happened on the stock kernel and it also happens with this new test kernel.

Just reporting my findings.

Performance is much better overall, but Large file transfers (like Win11.iso) between vlans still result in a complete lockup of the router when Zenarmor is active. All vlans are on the same parent interface (ix0) which is monitored by Zenarmor.

I am also seeing 100% A+ ratings on waveform bufferbloat test with Shaper configured. I used to see an A rating with moderate increase in buffebloat. It's absolutely zero now with a consistent A+. Even without Zenarmor, I'll be running this kernel for awhile. Thank you all for your efforts to improve the platform.

I'm also stuck in the exact same spot after uninstalling/reinstalling Zenarmor. Have you been able to work this out yet?
