Re: [Openvpn-users] how-to realise mixed circular vpn and star vpn

Hi
I suggest you to use the client-config-dir option. In this directory you
will put a file per client's CN.
According to openvpn's man:
"This  file can specify a fixed IP address for a given client using
--ifconfig-push, as well  as  fixed  subnets  owned  by  the client
using --iroute.
...
The following options are legal in  a  client-specific  context: --push,
--push-reset, --iroute, --ifconfig-push, and --config."

Hope this help
Jean Baptiste Favre
