The sessions are on different VLANs, but they are handled by the same AC that doesn't allow that both sessions are initiated by the same MAC address. Is there a way to associate two MAC addresses to a single physical interface (even by creating a virtual interface linked to the physical one) and so have VLANs on different mac addresses, without forcing the use of a secondary physical interface? -- Alex Dupre
