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
IMPORT THE CERTIFICATES
/certificate import file-name=cert_export_CA-%MikroTik Identity%.crt passphrase="" /certificate import file-name=cert_export_client-%Client Name%.crt passphrase=%Passphrase% /certificate import file-name=cert_export_client-%Client Name%.key passphrase=%Passphrase%
The Certificates window should now look similar to this screenshot.
MIKROTIK A (SERVER): OPENVPN PPP CONFIGURATION IMPORT THE CERTIFICATES
/ppp profile add name=openvpn local-address=192.168.200.254 remote-address=192.168.200.10 change-tcp-mss=yes use-compression=no use-encryption=required
OR Navigate to PPP > Profiles and create a new PPP Profile (modify settings as needed):
In the screenshot above, don’t forget to check the protocols tab. Under the protocols tab, the option for “Use Compression” and “Use Encryption” can be set. These two options are already set in the command, but cannot be seen in the screenshot. In addition, take note of the Local and Remote IP addresses (192.168.200.254 and 192.168.200.10), these two addresses define the static IP assigned to each end of the VPN tunnel. These IP addresses can be set to anything you want as long as they don’t match any of the existing subnets that are currently in use at each site.
