vietvpn
I use the plugin:
plugin /usr/lib64/openvpn/plugin/lib/openvpn-auth-pam.so login
client-cert-not-required
username-as-common-name
How all the servers using general account 1 VPN server?
For example:
Server1.openvpn.net main server contains accounts
sv2.openvpn.et, sv3.vietvpn.net ... use the account server 1 connect VPN
