Secure Socket Tunneling Protocol (SSTP) is a VPN protocol designed to transport PPP traffic via a secure SSL/TLS channel.
 +
 +
This article provides a guide on how to configure '''SSTP''' tunnel between RUTxxx (client) and Mikrotik (server) routers.
 +
 +
==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==

==Mikrotik (server) configuration==
 +
 +
Connect to MikroTik by using '''WinBox''' application and press '''New Terminal'''.

Prerequisite for any VPN server is to get certificates sorted. Procedure is exactly the same as for OpenVPN server setup with the slight difference being that common-name really matters. It must match either external IP or external host name – no exceptions. Use these commands to create certificates:
 +
 +
/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
 +
 +
sign ca-template name=ca-certificate
 +
 +
sign server-template name=server-certificate ca=ca-certificate
 +
 +
sign client-template name=client-certificate ca=ca-certificate
 +
 +
You will need to export root certificate, to do so use these commands:
 +
 +
/certificate
 +
 +
export-certificate ca-certificate export-passphrase=""
 +
 +
Instead of editing the default encrypted profile, we can create a new one. Assumption is that your MikroTik will also be a DNS server. And while at it, create 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
 +
 +
Enable SSTP VPN server interface:
 +
 +
/interface sstp-server server
 +
 +
set enabled=yes default-profile=vpn-profile authentication=mschap2 certificate=server-certificate force-aes=yes pfs=yes
 +
 +
Do not forget to adjust firewall if necessary (TCP port 443):
 +
 +
/ip firewall filter
 +
 +
add chain=input protocol=tcp dst-port=443 action=accept place-before=0 comment="Allow SSTP"
 +
 +
Now go to '''Files''' and export the certificate by simply dragging it to your desktop.
 +
 +

 +
 +
==RUTxxx (client) configuration==
 +
 +
Access RUTxxx WebUI and go to '''Service > VPN > SSTP'''. There create a new configuration by writing configuration name and pressing '''Add''' button. It should appear after a few seconds. Then press '''Edit'''.
 +
 +
[[File:Networking_rutxxx_configuration_example_sstp_mikrotik_2_v1.png|border|class=tlt-border]]
 +
 +
Now apply the following configuration.
 +
 +
[[File:Networking_rutxxx_configuration_example_sstp_mikrotik_3_v1.png|border|class=tlt-border]]
 +
 +
# '''Enable''' Instance.
 +
# '''Write Server IP address''' (MikroTik public IP address).
 +
# Write '''Username''' (write the username which you created with this command: secret add name='''user''' profile=vpn-profile password=password).
 +
# Write '''Password''' (write the password which you created with this command:  secret add name=user profile=vpn-profile password='''password''').
 +
# Upload '''CA cert''' (the file which you exported from MikroTik).
 +
# Press '''Save'''.
 +
 +
==Testing configuration==
 +
 +
Go to '''Status > Routes''' and in the '''Active IP Routes''' table you should see this new route.
 +
 +
[[File:Networking_rutxxx_configuration_example_sstp_mikrotik_4_v1.png|border|class=tlt-border]]
 +
 +
Try to ping the remote VPN endpoint via '''CLI''' or '''SSH''' using this command:
 +
 +
ping 192.168.8.250
