New to the Meraki and I have been reading documentation but do not feel I have found the right solution, hoping for some clearer direction here. After a security breach, we bought new Meraki MX-95 and MS125-48 to build out an entirely new network on a 172 network. Our old network was a 192. We will need to do a one-way trust to transition users over. The original plan was to dedicate one port on the MX-95 for the old 192 network then limit traffic to just let in the needed ports and protocols for the one way trust to come in to the new 172, but exclude all other traffic as we feel there is probably still issues on the old network. We currently use Sonicwall and are finding the new Meraki rules a whole new way of thinking. I guess the question we have is are we on the right track using the firewall rules to exclude incoming traffic on one port. If we are, any suggestions are appreciated. We are still educating ourselves on the MX-95. Thank You.
