TLS payload ciphertext (n bytes) (only for P_CONTROL_V1). Note that when –tls-auth is used, all message types are protected with an HMAC signature, even the initial packets of the TLS handshake. This makes it easy for OpenVPN to throw away bogus packets quickly, without wasting resources on attempting a TLS handshake which will ultimately fail.
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm in the middle of re-configuring my OpenVPN (which died due to a server crash). I have the Server configured and all the certs/keys built for my clients. I have successfully set up a tunnel between the server and my DD-WRT enabled router, a Linksys NSLU2 and also a VPS.

Prepend a one-byte OpenVPN data channel P_DATA_V1 opcode to the packet. More void tls_prepend_opcode_v2 (const struct tls_multi *multi, struct buffer *buf) Prepend an OpenVPN data channel P_DATA_V2 header to the packet. More void tls_post_encrypt (struct tls_multi *multi, struct buffer *buf) Perform some accounting for the key state used
Added new packet format P_DATA_V2, which includes peer-id. If server supports, client sends all data packets in the new format. When data packet arrives, server identifies peer by peer-id.
I also tried this with viscosity. pfsense logs: 126.96.36.199:1194 Authenticate/Decrypt packet error: bad packet ID (may be a replay): [ #1 / time = (1534446687) Thu Aug 16 15:11:27 2018 ] -- see the man page entry for --no-replay and --replay-window for more info or silence this warning with --mute-replay-warnings Aug 16 15:11:27 openvpn 83547 188.8.131.52:1194 TLS Error: incoming packet
