IP Range

[derekoccland]

Hi, I have setup my openvpn server on a VPS. And I controll it with the gui interface. But every time one client reconnect to vpn the ip of client incrase at 1 (for example: my ip is 172.27.248.2 i press reconnect become 172.27.248.3 etc etc) it's dangerous? Can I give you the first available ip? I had thought of setting a static ip, but then if it connects 2 devices with the same profile can it be a problem?

Thanks and sorry for my bad english

Do not use the same client certificate for all your devices.

Why? Its more "comfortable" for clients

No it is not .. it is just easier for a lazy admin.

Add --explicit-exitnotify 3 to your client config file and it will tell the server it is disconnecting and then use disconnect not reconnect.
