− | 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'''.

| |
− | 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 New''' button. It should appear after a few seconds. Then press '''Edit'''.

| |
− |
| |
− | Then apply the following configuration.
| |
− |
| |
− | [[File:Networking_rutxxx_configuration_example_ovpn_mikrotik_4_v1.jpg|border|class=tlt-border]]
| |
− |
| |
− |
| |
− | # '''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==
| |
− |
| |
− | Go to '''Status > Routes''' and in the '''Active IP Routes''' table you should see these two new routes.

| |
− |
| |
− | Try to ping the remote VPN endpoint via '''CLI''' or '''SSH''' using this command:
| |
− |
| |
− | ping 192.168.8.250
