I agree try AES-NI (in cpu) read this please, especially the reply from "jimp" https://forum.netgate.com/topic/114212/aes-ni-cryptodev-openvpn-help-a-n00b-understand/16

The setting is in :

System/Advanced/Miscellaneous

try it and see how it performs.

daemonix

fast-io
sndbuf 524288
rcvbuf 524288

added this, changed my PIA client to GCM (my server was already GCM) and I already had just the hardware acceleration only...
Gone from 45-sih mbit to 70-70mbit in both PIA and my server!!!

Does this mean that "AES-NI CPU-based acceleration" is better than the "AES-NI and BSD Crypto Device" option? I'm still confused what the difference between those two are.

Yes! The Apu2 does not have a dedicated Crypto-Device, the Crypto-Functions are integrated in the CPU (much faster). IMHO

I see. But won't it use AES-NI anyway if the latter option is selected?

Also, in the OpenVPN settings you should chhose None in the Hardware Acceleration field, correct?

Freebsd will look for the Crypto-Device wich is not existent and will not fallback to AES-NI CPU based.

I admit I dont know. Sorry.

Yes this is it. I did all the possible test combinations.
Indeed ONLY AES-NI should be selected

Yes, the only thing to avoid here is enabling both aes-ni and bsd crypto. Doing that will cause the aes device to register for crypto acceleration via the framework which adds a load of additional steps. It's much faster to use the available CPU instructions directly. As long as it's enabled in the BIOS openssl, and hence openvpn, should use aes-ni.

So you have to select AES-NI in pfSense and not in OpenVPN, then why is this option (Hardware crypto) present in OpenVPN config within pfSense? Could you please clarify this?

Cheers Qinn

I have personally never used that setting. But I have also never had a device with a specifically supported hardware crypto device which is where I would expect it to apply.
In testing I did when we went to OpenVPN 2.4 it was better to leave that set to None in every case.

@stephenw10 kudos for clearing that one up!

Don't want to crush this topic (and can't PM you) but lemme ask how far crypto in the SG-1100 has come? Last thing I know is that HW is present and waits for the software to follow. Anything changed in this regard?

stephenw10

That is still basically the status. I'm not sure how far along that work is, I did see some discussion of it a few days ago.

But that's a good point. On the SG-3100 where the crypto hardware is supported via the CESA driver I am currently running with BSD Crypto device set in both OpenVPN and as the system crypto device.

Although it is not downloadable at the moment, did anyone tried the new v4.10.0.0?

Have you download it?

kevindd992002

Do you guys have any issues with the download links for v4.10.0.0? They're all "404 page not found" for me. Or were they removed intentionally?

Qinn

@kevindd992002 Yes, I don't think it's build

Just updated. Link is properly working. No issues so far.
