[SOLVED] Bad openVpn client config ?
stef33560 last edited by
My ubuntu's OpenVpn client is this :
client dev tun proto udp remote <<remoteip>> 1194 resolv-retry infinite nobind persist-key persist-tun ca /path/to/my/CA.pem cert /path/to/my/me.pem key /path/to/my/me.key ns-cert-type server comp-lzo verb 6 up update-resolv-conf down update-resolv-conf</remoteip>
The result :
$ openvpn testvpn ???.conf

Does somebody can explain me the error, or rather give me a sample client configuration ?
Thanks a lot !

A /30 will only work if you set up this with a shared key.
For site-to-site you should use a shared key.
Yes you will have to set an interface IP, because with a shared key no routes/IPs/DHCP-settings/anything will be pushed from the server.
The configuration is only what you put into the config file.
The reason why a /30 with a PKI won't work:
In a PKI you have the x.1 IP for the server.
Every time a client connects a new dynamic /30 subnet is added to the virtual interface.
x.0/30 initial IP of the Server.
x.4/30 first client (x.5 server, x.6 client)
x.8/30 second client (x.9 server, x.10 client)
This ensures that the clients can talk only with the server and not with each other directly.
