Mikrotik RB750 as OpenVPN client with TLS-auth

I have an Linux OpenVPN server, also i have my RB750 with client certificate and private key imported.

When I try to connect RB750 to Linux OpenVPN server this message appear in server logs:

Thu Oct 24 11:48:38 2013 us=177236 87.249.250.221:60958 TLS: Initial packet from {client ip and port}, sid=054616eb 1c1735a8

I have no idea how to import ta.key in RB750 for TLS-auth.
I tried to do it in a standard way through the certificates meny, but no luck.

Any suggestions?

Can I use a TLS-auth with Mikrotik?

Thanks, and sorry for my english.

No, and LZO is also unsupported.

Any news? Four years have passed.

I don’t think it will get double digit ever.
