Hi,
I read this: - -push option Push a config file option back to the client for remote execution...
that's what I put in client config or it is an argument for openvpn-gui.exe .... can you give me a clue?
thanks

The Manual wrote: The client must specify --pull in its config file

I put in client config file

Code: Select all

--pull compress lz4-v2

but got this error
Options error: Unrecognized option or missing or extra parameter(s) in config.ovpn:123: pull (2.4.7)
found nothing on manual about enabling lz4-v2 on client side
thanks

seems that for v2.4+ clients no compression specific config required at the client end as long the above config is 'pushable'
but on client side I got
WARNING: 'comp-lzo' is present in remote config but missing in local config, remote='comp-lzo'

In server config I have one line commented:
# comp-lzo

You can safely ignore that message .. it is a bit of a bug.
