MIKROTIK A (SERVER): CERTIFICATE SETUP & EXPORT

CREATE THE CERTIFICATES

/certificate add name=ca-template common-name=CA-HQ key-usage=key-cert-sign,crl-sign
/certificate add name=server-template common-name=SERVER
/certificate add name=client-Cabang-template common-name=client-Cabang

SIGN THE CERTIFICATES

Butuh waktu, jangan copy paste sekaligus.

/certificate sign ca-template ca-crl-host=192.168.88.198 name=CA-HQ
/certificate sign ca=CA-HQ server-template name=SERVER
/certificate sign ca=CA-HQ client-Cabang-template name=client-Cabang

ENABLE “TRUSTED” FOR THE CERTIFICATE AUTHORITY AND SERVER ONLY

/certificate set CA-HQ trusted=yes
/certificate set SERVER trusted=yes

The Certificates window should now look similar to this screenshot.

EXPORT THE CERTIFICATES

/certificate export-certificate CA-HQ
/certificate export-certificate client-Cabang export-passphrase=123456789

Ambil file menggunakan FTP

cert_export_CA-HQ.crt
cert_export_client-Cabang.key
cert_export_client-Cabang.crt

MIKROTIK B (CLIENT): CERTIFICATE SETUP & IMPORT

Upload file menggunakan FTP

cert_export_CA-HQ.crt

/certificate import file-name=cert_export_client-Cabang.crt passphrase=123456789
/certificate import file-name=cert_export_client-Cabang.key passphrase=123456789
