OpenVPN Version in RUTX50 v7.05.4 ? (Cipher Suite Negotiation)

[BSeklecki]

Which OpenVPN version is embedded?

I’m trying to sort out the best compatible client as per the CIPHER SUITE negotiation problem identified in thread: OpenVPN on RUTX50

The community OpenVPN Client available for non-POSIX platforms as of December 2023 is: OpenVPN-2.6.8-I001-amd64.msi

Correct me here ( but the the OpenVPN community is not one that easily provides unambiguous data), but my understanding is that Versions/branches v2.5.x and v2.6.x were the transitionary branches where many legacy cipher suites were disabled.

AES-256-CGM and AES-256-CBC are standard now and clients cannot connect to many older v2.4 servers.

Thanks,

FYI I’m only able to make the v2.6.x client connect to the latest RUTX50 if I define a failback Cipher Suite with “data-ciphers-fallback” option pointing to an old 128bit AES CBC.
