Would an OpenVPN server running on a firewall allow for network segregation?

When a client connects to the AP the DHCP server gives them an address
in a network. The firewall could allow NATed access out
to the net on 80 and 443 from that address range.

If the client then connects to the VPN the DHCP server would give them
another IP in a network. The firewall would then allow
open (NATed) access from through the VPN device to the
outside network.
