I have a Guest network set up in our Meraki Organization using a Z3 appliance. It is the DHCP server for the guest network. We have a main office network including MX100s, MS225s, MS250s and Wireless Access Points. There is a link between our Guest Network and Main network to allow clients connecting to the wireless access points to gain access to the DHCP service and network hosted on the guest gateway. (Access ports on the VLAN hosted on the Z3 that connects to an access port on the Main network on the same VLAN).  I attempted to create an interface on the Z3 for a network hosted on the L3 switches in our main network, update the uplink ports to allow the same network on the uplink ports and created static routes on both ends. Saving these changes triggered errors, which I can provide photos of.  The problem I am trying to solve is allowing client devices on the Guest network (Z3 hosted) to reach certain devices on the main network. It seems like the way I tried should work, but I am getting errors on both sides and not sure how best to proceed with solving this.      ... View more
