Good evening friends,

I’m trying to close a tunnel in OVPN Mikrotik as client and server is Linux - OpenVPN, use the encryption key, the key MikroTik care in public and private, but the server uses DES-EDE3 and could not hit the MikroTik OVPN_Client settings. See below the error that appears in the LOG Linux.

Hi sir

RouterOS OpenVPN does not support LZO compression so disable it on Linux server side and it will work as expected.

from openvpn config file

This option defines whether to use LZO compression.

If enabled, it must be enabled at both ends of the VPN connection.

#comp-lzo

hoping this will help you.

have a nice day
