@RicardoBR I am sure what your issue is. Describe your setup.

@Clive_A I have solved my issue which was caused by a wrong type of certificate. And i have a test running where ER605 connects as OpenVPN client to af pfSense 2.7.2 OpenVPN server Trouble shooting...

I need to use standalone ER605 as a OpenVPN client to a pfSense OpenVPN server, which is raises some issues on the product documentation. It is not specified which cipher suites ER605 supports?...
