That's a nice gesture, thank you. However, I don't think it'll work for me. I can't seem to renew before my renewal date of 12/9 when it's set to autorenew. At that point, the promotion will have ended. I also cannot purchase a new subscription with this promo since my current subscription is active. Appreciate the gesture but I think it would only work if my renewal was due within the promotion window, which it is not.

Did I read the pop-up correctly that it only works for new customers?

Feedback just sent!

I'm really liking the 1.16 update thus far.  :)

One observation from my network is that a significant chunk of what I believe to be mDNS traffic (port 5353) from mostly Apple devices is being flagged as a threat - Malformed Dns Packet. The good thing is that even with the Malformed Dns Packet advanced security policy enabled, it isn't blocked. But it is throwing the threat numbers to be up significantly, so there are more false positives to filter through.

There does seem to be a pattern. I'm running a mDNS repeater on the OPNsense so that wireless devices can see the wired printer for AirPrint. So, a majority of the wireless devices aren't flagged as Malformed Dns Packet but properly as mDNS as they are connecting with mdns.mcast.net (224.0.0.251) on my network. Occasionally, an Apple TV over wireless is flagged as malformed when it sends port 5353 packets to the gateway on OPNsense. However, what triggers the threat most are the wired devices such as my Macbook (when wired in), my Synology (wired), or my Denon receiver (wired), as they are sending frequent port 5353 packets to the gateway on OPNsense. Conversely, the wired printer, doesn't do this but mostly sends to mdns.mcast.net (224.0.0.251).

Not a big deal, but I'm wondering if there's anyway for this type of mDNS traffic to not be labelled as "Malformed Dns Packets"? I would think all that's needed is to filter out the port 5353 traffic. I'm not aware of that being used for normal DNS.

However, driver incompatibility problems, like igc, are not in the scope of this project.
After the current project is accomplished successfully, they are going to start a new project to improve emulated netmap mode.

The main aim of the second project is to solve incompatibility problems for all drivers. It is intended to be able to provide quick support to the new NICs as well.

Lastly, it is needless to say that the success of these projects mostly depends on community support, and feedback from community members, like you, is priceless.

I'm not sure exactly when this occurred but sometime after I installed 23.7 or zenarmor 1.14 (started with 23.7.3 as I waited awhile and now on 23.7.4 and updated to 1.14/1.15 zenarmor), my issues vanished with the emulated driver. Everything seems to be working as designed with netmap. Performance is great and policies are working as they should. Traffic is actually being blocked now and netmap isn't crashing. Really excited that this is working as it should. I do not currently have vlan tags, so I can't verify if that is an issue. That was something I eliminated earlier in my troubleshooting process.

Running Protectli VP2420 with Intel I225-V 2.5G NICs and igc driver.

Exact same issue here, kill -9 of crowdsec-firewall-b resolved the issue for me too. Thank you!

Hi SpinningRust,
Could you confirm that this issue occurs in emulated mode?
Best

Yes, the issue definitely does occur in emulated mode. I reported my logs in the other testing thread that franco setup.

I was trying out the new netmap2 kernel that franco just released. I did not expect it to resolve zenarmor's issues with netmap for my igc(4) driver, and I confirmed it didn't, but this reminded me of another observation...when I do enable zenarmor in L3 routed mode, my upload bandwidth is significantly reduced. In passive mode I consistently get 15-17Mbps but in L3 routed mode upload is reduced to 2-7Mbps. Download bandwidth remains unaffected at around 940Mbps. It's capped by my 1Gbps switch between the firewall and my computer. Just thought I'd throw that observation out there.

Thanks for opening this thread DoBoY and thank you to beki and mb for the honest feedback. I am using the igc(4) driver with the I225-V interfaces on my Protecli box. My problem is well described in Franco's testing thread so no need to describe further here. I have no intention to hijack another thread. :-)

mb/beki: Feel free to PM me if you ever need a tester in the future. I appreciate the approach you will be taking and that it is on the roadmap. Regards.

Today I decided to see if there was a firmware upgrade for my NIC, which there wasn't, but on the odd note, I did let the system fully turn off, and turn on and now it works.

I know when I removed all vlans from my config to see if that was causing my netmap issues, it took a full reboot for the vlan interfaces to disappear from zenarmor. Perhaps it's that way with additions as well. It was removed from OPNsense config right away, but zenarmor continued to see the vlan interfaces until I rebooted.

Also...the native netmap driver is working great too. It's like a night and day difference. Having no issues thus far. :-)

Unfortunately I was wrong. User error. My custom policy in Zenarmor showed it was enabled and actively running, but it wasn't, so Netmap hasn't been running at all since the upgrade 2 nights ago. Must have been something with the 23.1.1 update that had the setting toggled incorrectly.

I noticed something was off when the reports didn't show anything blocked or even as a threat in my custom pollcy. Creating a blocklist item for a test domain also wouldn't be blocked and only pass through the default policy. Once I tickled my custom zenarmor policy off and then on again, it began to work as desired...and all my netmap problems returned. Bummer!

Back to passive mode I go.

Here is what I see in dmesg with native netmap:

Donated.
Thank you, thank you, thank you. Very grateful!

The instructions in this article worked perfectly for me. I moved to different hardware and switching from 1Gbps to 2.5Gbps interfaces with different names as well as locations for WAN, etc. This article lays out what to look for when making changes. Highly recommend reviewing it.
https://homenetworkguy.com/how-to/migrate-opnsense-to-new-hardware/

Also...the native netmap driver is working great too. It's like a night and day difference. Having no issues thus far. :-)

So far so good. I've been running on the 23.1.1 build with no netmap issues. Even when netmap worked for me before,dmesg would show lots of dtor, attach, register, unregister entries. None of that since in the last 9 hours or so for me with no interface flaps.

Looking promising...
