Restricting VPN user to specified subnets

[jason.winters@psma.com.au]

New to Opensense and have run into an interesting issue.
How do you limit aVPN user to access only certain subnets once they have authenticated?

The firewall rules do not seem to provide an option to check for a user or group in order to form up the rules.
Its quite possible I am looking in the wrong place too.

Help greatly appreciated.
