Basics
To create a VPN rule, add an item under the Rule collection hive and select VPN Rule.
Give the rule a Name that explains for what the rule is used for. Furthermore, a descriptive name will help you to identify authentication requests processed by this rule in your logs easily later on.
Do not forget to Enable the rule!
Authentication
Under the Authentication hive, your first choice is whether you want to allow or decline Certificate-based or Username/Password-based authentication for this rule.
Certificate-based Authentication
For certificate-based authentication you have the following choices to further constrain incoming authentication requests.
Allow only specific CAs (Trusted Roots)
This allows you to narrow down incoming authentication requests to specific trusted root CAs. Those CAs can be a subset of all Trusted Roots you have configured on the RADIUSaaS platform.
Filter for Intune IDs
This is a historical setting. If your clients are authenticating with certificates that your clients received during the AAD-Join, you want to filter for your Intune Tenant ID.
In case you have entered your Tenant IDs as described here, the default behaviour of RADIUSaaS is that only machines presenting a certificate with extension OID 1.2.840.113556.5.14 and a whitelisted value for the Tenand ID will get access to the network. With the rule engine, you now have the option to further restrict the access to specific Intune IDs for a specific rule or to ignore the certificate extension. This allows you to have a multi-deployment setup, where some clients come with certificates providing the respective OID and some do not.
Username/Password-based Authentication
After enabling Username/Password-based authentication, you can apply additional filtering by configuring a Regex on the Username. Default is all Usernames
Configuration
Under the Configuration hive you are able to configure additional filter criteria based on the origin of authentication requests as well as return additional RADIUS attributes, e.g. Filter-Id.
NAS Identifier Filter
In case you are unsure what identifier your NAS uses, you can check the logs (Logtype = detail). RADIUSaaS looks for a propety called NAS-Identifier to match against the trusted NAS Identifiers.
To set a NAS Identifier filter, either select Identifiers or Groups.
If you select Identifiers, you can specify multiple Identifiers.
If you select Groups you can reference one or more of your pre-defined NAS Identifier Groups.
NAS IP Address Filter
To set a NAS IP address filter, either select IPs or Groups.
If you select IPs, you can specify multiple IPs.
If you select Groups you can reference one or more of your pre-defined NAS IP Address Groups.
RADIUS Attribute Return
In case you require return attributes that are not available by default, please contact our support.
The RADIUSaaS rule engine provides several ways to return additional RADIUS attributes. The following options are available:
Static
Statically specify the return attribute(s) and their value(s) which should be assigned based on the related rule.
By Certificate Extension
Currently it is not supported to add custom certificate extensions to SCEP profiles in many MDM systems, including Microsoft Intune and JAMF.
We therefore recommend to use the Certificate Subject Name of the certificate instead to add a VLAN assignment.
Select one of your created Certificate Extensions
The filter is set to match the Value of the specified return attribute to your specified extension (OID)
Wildcards will be translated to .* Regex
By Certificate Subject Name Property
You can also return additional RADIUS attributes based on properties in the Subject Name of your certificate
Therefor, specify in which property the return attribute value is stored
Then, configure which string the return attribute value is prefixed with
The value provided in the Subject Name property is not required to have a prefix. However, it can be required to use a prefix in case your Subject Name carries the same attribute more than once (e.g. several CN's are quite common).
