==Introduction==

OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities.

This guide provides a configuration example with details on how to configure OpenVPN connection between MikroTik and RUTXxx routers. The server will be MikroTik device and the client will be our RUTXxx router.

==Prerequisites==

* One RUTXxx router of any type
* One Mikrotik router (this configuration example was created using Mikrotik rb750gr3)
* Server must have a Public Static or Public Dynamic IP address
* At least one end device (PC, Laptop) to configure the routers
* WinBox application

==Configuration scheme==

==Server (Mikrotik) configuration==

Connect to MikroTik by using '''WinBox''' application and press '''New Terminal'''.

[[File:Networking_rutxxx_configuration_example_l2tp_ipsec_mikrotik_1_v1.jpg|border|class=tlt-border]]

Now create certificates by using these commands (these will be valid for 10 years): 

 /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

Created certificates will need signing, use these commands:

 sign ca-template name=ca-certificate

 sign server-template name=server-certificate ca=ca-certificate

 sign client-template name=client-certificate ca=ca-certificate

Now you need to export those certificates: 

 /certificate

 export-certificate ca-certificate export-passphrase=""

 export-certificate client-certificate export-passphrase='''12345678'''

Now go to '''Files''' and export those certificates by simply dragging them to your desktop.

Now go back to '''Terminal''' and create a separate pool of IP addresses for clients by using this command:

 /ip

 pool add name="vpn-pool" ranges=192.168.8.10-192.168.8.99

Instead of editing the default encrypted profile, we need to create a new one. Assumption is your MikroTik will also be a DNS server. And while at it, create a bit more secure user/password:

 /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='''password'''

Adjust firewall by using this command:

 /ip firewall filter

 add chain=input protocol=tcp dst-port=1194 action=accept place-before=0 comment="Allow OpenVPN"

Now enable OpenVPN server interface:

 /interface ovpn-server server

 set default-profile=vpn-profile certificate=server-certificate require-client-certificate=yes auth=sha1 cipher=aes128,aes192,aes256 enabled=yes

==Client (RUTXxx) configuration==

Access RUTXxx WebUI and go to '''Service > VPN > OpenVPN'''. There create a new configuration by selecting role '''Client''', writing '''New configuration name''' and pressing '''Add''' button. It should appear after a few seconds. Then press '''Edit'''.

[[File:Networking_rutx_configuration_example_ovpn_mikrotik_3_v1.png|border|class=tlt-border|1100x1100px]]

Then apply the following configuration. 

[[File:Networking_rutx_configuration_example_ovpn_mikrotik_4_v1.png|border|class=tlt-border|1100x1100px]]

# '''Enable''' Instance.
# Select '''Protocol''' (TCP).
# Select '''Authentication''' (TLS/Password).
# Select '''Encryption''' (AES-128-CBC 128).
# Write '''Remote host/IP address''' (MikroTik public IP address).
# Write '''Keep alive''' (10 120).
# Write '''Remote network IP address''' (192.168.8.0).
# Write '''Remote network IP netmask''' (255.255.255.0).
# Write '''User name''' and '''Password''' which you created on Mikrotik (you created it by using this command: secret add name='''user''' profile=vpn-profile password='''password''').
# Upload '''Certificate authority''', '''Client certificate''', '''Client key''' (use those exported files).
# Write '''Private key decryption password''' (you created it by using this command: export-certificate client-certificate export-passphrase='''12345678''').
# Press '''Save'''.

==Testing configuration==

Try to ping the remote VPN endpoint via '''CLI''' or '''SSH''' using this command:

 ping 192.168.8.250
