Hi @tantony The MX doesn't require an internet connection to continue to function and route VLAN's. In the setup you have mentioned the VLAN's should be working, assuming the ports have been setup correctly along with the firewall rules. Can you connect the MX to the internet to perform the test to examine what is taking place? However any configurations made in the dashboard will not be applied to the MX until it has connected. Without a Dashboard connection you will be very limited in what you can do with the MX and what you can see. If you are unable to supply the MX with a connection to Dashboard then you may be better going with a device with onboard management rather than Cloud management.
