Certificate
Certificate Generate
/certificate add name=ca-template common-name=example.com days-valid=3650 key-size=2048 key-usage=crl-sign,key-cert-sign add name=server-template common-name=*.example.com days-valid=3650 key-size=2048 key-usage=digital-signature,key-encipherment,tls-server add name=client-template common-name=client.example.com days-valid=3650 key-size=2048 key-usage=tls-client add name=client1-template common-name=client1.example.com days-valid=3650 key-size=2048 key-usage=tls-client
Certificate Sign
SATU PER SATU, jangan COPAS Sekaligus. Proses signing akan membutuhkan waktu, harap sabar.
/certificate sign ca-template name=ca-certificate sign server-template name=server-certificate ca=ca-certificate sign client-template name=client-certificate ca=ca-certificate sign client1-template name=client1-certificate ca=ca-certificate
Certificate Trust
/certificate set ca-certificate trusted=yes set server-certificate trusted=yes
Certificate Export
/certificate export-certificate ca-certificate export-passphrase="" export-certificate client-certificate export-passphrase=123456789 export-certificate client1-certificate export-passphrase=123456789

OpenVPN Server di Mikrotik
OpenVPN Pool Address
/ip pool add name="vpn-pool" ranges=192.168.8.10-192.168.8.99
OpenVPN user
/ppp profile add name="vpn-profile" use-encryption=yes local-address=192.168.8.250 dns-server=192.168.8.250 remote-address=vpn-pool secret add name=user profile=vpn-profile password=123456 secret add name=user1 profile=vpn-profile password=123456 secret add name=user2 profile=vpn-profile password=123456 secret add name=onno profile=vpn-profile password=123456
OpenVPN Enable
/interface ovpn-server server set default-profile=vpn-profile certificate=server-certificate require-client-certificate=yes auth=sha1 cipher=aes128,aes192,aes256 enabled=yes
PC Kali Linux
Download crt & key
cd /etc/openvpn/client
ftp (IP OpenVPN Mikrotik) 192.168.0.219 username admin password mget * quit
Edit client.ovpn
client dev tun proto tcp # remote (IP Mikrotik OpenVPN) 1194 remote 192.168.0.219 1194 resolv-retry infinite nobind persist-key persist-tun ca /etc/openvpn/client/cert_export_ca-certificate.crt cert /etc/openvpn/client/cert_export_client-certificate.crt key /etc/openvpn/client/cert_export_client-certificate.key remote-cert-tls server cipher AES-256-CBC auth SHA1 auth-user-pass # redirect-gateway def1
PC Run OpenVPN
cd /etc/openvpn/client sudo openvpn --config client.ovpn
Enter Auth Username: user Enter Auth Password: password Enter Private Key Password: 12345678
PC Client
PC Download File
Bisa di download ke PC / client menggunakan ftp, file yang dibutuhkan adalah
cert_export_ca-certificate.crt cert_export_client-certificate.crt cert_export_client-certificate.key
Nantinya bisa di rename menjadi
ca.crt, client.crt, & client.key
dengan ftp
cd /etc/openvpn/client ftp 192.168.88.198 username admin password
mget * quit
cd /etc/openvpn/client mv cert_export_ca-certificate.crt ca.crt mv cert_export_client1-certificate.crt client1.crt mv cert_export_client1-certificate.key client1.key mv cert_export_client-certificate.crt client.crt mv cert_export_client-certificate.key client.key
PC Buat Konfigurasi ovpn
Edit hosts supaya mengenali VPN Server
vi /etc/hosts
192.168.88.198 example.com
IP 192.168.88.192 adalah IP VPN Server. Buat client.ovpn
cd /etc/openvpn/client/ sudo vi client.ovpn
client dev tun proto tcp remote example.com 1194 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key remote-cert-tls server cipher AES-128-CBC auth SHA1 auth-user-pass redirect-gateway def1
PC Run OpenVPN
cd /etc/openvpn/client sudo openvpn --config client.ovpn
Enter Auth Username: user Enter Auth Password: password Enter Private Key Password: 12345678
PC Cek
Pastikan ada interface tun
ifconfig
tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500
inet 192.168.8.99 netmask 255.255.255.0 destination 192.168.8.99

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1328 bytes 148649 (148.6 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Pastikan ada routing
netstat -nr
192.168.8.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0
verb 3 A bit annoying step is being asked for the private key passphrase (in the addition to username/password). Mikrotik doesn’t allow export without it but fortunately we can use OpenSSL to change that:
> openssl.exe rsa -in client.key -out client.key Enter pass phrase for client.key: 12345678 writing RSA key With this, your VPN connection should work like a charm.
PS: Do not forget to adjust firewall if necessary (TCP port 1194).
/ip firewall filter add chain=input protocol=tcp dst-port=1194 action=accept place-before=0 comment="Allow OpenVPN"
PPS: Do check SSTP guide too.
[2017-01-26: Adjusted certificate creation to work on RouterOS 6.38 and later] [2017-01-26: Changed key size to 2048 (instead of 4096) so it doesn’t take ages to generate certificates. :)] [2017-02-25: Changed example to use AES-128 for lower CPU usage on router.]
