I've been setting up Meraki devices for a few years now, and have noticed (invariably) there is more than one place to configure Layer 3 firewall rules. You can do it in the Addressing & VLANS section, and apply it to an entire VLAN and you can also apply it in the Wireless --> Firewall & Traffic Shaping section. [long silent pause]. I think just by typing this I may have answered my question, but, what is the difference in adding a Layer 3 firewall rule on the VLAN (in Addressing & VLANS) versus applying/configuring the Layer 3 firewall rules in Wireless --> Firewall & Traffic Shaping? In the wireless section, would those rules only apply to wireless clients, and, if a client is on the same VLAN, but WIRED, those rules would NOT apply?
I ask because I have about 5 MR42 access points connected to a MX67 and I created Layer 3 firewall rules on the VLAN on the MX67, rather than in the Wireless --> Firewall & Traffic Shaping section. This VLAN is dedicated entirely for wireless, so the fact I mentioned a WIRED client on this same VLAN might be irrelevant. I'm just wondering what the differences of applying these rules in each area are, or, if it's all the same.
I read on THIS PAGE that "All other settings would be inherited from network defaults". So if I leave the Wireless --> Firewall & Traffic Shaping section alone, am I good since these Layer 3 ruels are applied on the VLAN defined on the MX67? I have already tested VLAN interconnectivity, and it behaves the way I imagined/configured but am wondering if I am doing it the wrong way.
