OpenVPN with TLS SNI (Server Name Indication)

Hi,

Does OpenVPN support TLS SNI, to be used by for example a reverse proxy on port 443.
If so, how can I configure this to be enabled? And will this use the Hostname set in the client config as SNI?

Kind regards,
Frederic Depuydt

Did you ever get an answer to this? It is possible to use the sslh proxy to detect the OpenVPN protocol.

I would like to use just port 443 to send OpenVPN traffic to two different OpenVPN servers.. a bridged server and a routed server.

Is it possible to use TLS SNI (maybe with sslh) to detect the domain name and thus filter to the correct server.

Thanks,
Flex
