AirVPN, PFSense & PCEngines

anon1701

I have to admit being stumped here.

Device 1: Virtual pfsense - lots of CPU and memory

Using Chow (Uk Server) on 2018 UDP

I get speeds of 170+Mb download

Device 2: PCEngines. Quad Core 1Ghz + Hardware Offload (AES256)

Using Chow on 2018 UDP

I get speeds of 55Mbps - no significant CPU useage that I can tell

Not using VPN - Speeds of 200Mb

Everything else is either the same or very similar

I may have to try pfsense on the PCEngine

Using beta.speedtest.net to test with

Did you verify that AES-NI is used?

In any case since OpenVPN is not multithreaded, 1GHz for a good OpenVPN speed is too low.

With pfSense you will be able to try aesni driver and native openssl support.

That was my tentative conclusion

No support for the hardware acceleration

Update:

I loaded pfsense onto the PCEngine

Used the same config from the software firewall (with a few nessesary tweaks like ethernet ports)

Navigated to system/advanced/Miscellaneous and changed the settings. I also tweaked the openVPN client settings to say use hardware crypto

Hardware Acceleration shows as working

Crypto Setting to AES-NI CPU & reboot

Result - about 56Mb

Ctypto Setting to AES-NI and BSD Crypto Device & reboot

Result - about 56Mb

Whatever I do I don't seem to get better than about 56Mb. I am dissapointed (not, I hasten to add, in AirVPN)

I think I shall go back to my virtual pfsense. With the pcengine unit back in th junk pile of other failed projects - got lots of them
