IPsec VPN from an iOS device to OPNsense connect and works fine, then just dies

« on: May 07, 2021, 12:53:09 pm »

Hi,

I've configured IPsec on my OPNsense DEC850, with AES256, SHA256 and DH-14. Works great for 20-30 seconds, then just stops passing traffic (user stays connected). I've tried different encryption and hash options, but nothing helps. I wonder if this has anything to do with the AES-NI acceleration bug...

any ideas?

Disable AES-NI Acceleration in system settings and try again, fastest way to find out if acceleration is the issue.
