4 modes are available:
•
PSK: used to establish a point-to-point OpenVPN
configuration.
•
SSL: Authentication is made using certificates only (no
user/pass authentication).
•
User Auth: Authentication is made using only CA, user and
password, no certificates. Useful if the clients should not
have individual certificates.
•

The default value is 1194.
Choose the encryption algorithm from the dropdown list to encrypt
data so that the receiver can decrypt it using same algorithm.

has an unmodified data from the one sent by the original host.
This option uses a static Pre-Shared Key (PSK) that must be

This feature adds extra protection to the TLS channel by requiring
that incoming packets have a valid signature generated using the
PSK key.
