ECC certificates SSL VPN
Allow the use of ECC certificates in place of the RSA certificates for SSL VPN. I realize ECC support was added in 17.5 but it was only partially implemented. The current (version 18 as of this writing) version of your firmware uses OpenVPN version 2.3.6. which does not support ECC. OpenVPN 2.4.0+ is required to support ECC. I had opened a support ticket, they confirmed the limitation and indicated there is no current upgrade timeline.
