Remote User Access different networks?

I see in this thread it’s been noted as On the Roadmap: Remote User Access for Different Users / Different Network Segments - #7 by Ron_Case

In the mean time, I wonder: is there any way to make it work NOW, using firmware 8.1.1?

For example:

  • set up an OpenVPN access with access to a specific VLANX for user1 and user2
  • enable inter VLAN routing
  • create a firewall rule denying all routing from VLANX to other networks
  • figure out user1’s MAC address and give them a DHCP reservation to a specific IP on VLANX
  • add a new firewall rule granting that IP access to cross from VLANX to the main LAN

Would this work?
