Hey folks,   I've seen this come up a few times, but haven't had any luck resolving this. Here's my issue: Wireless clients connected to the Guest VLan can't access my on prem Exchange server. I have the Meraki handing out DHCP addresses. I have public DNS servers for name resolution. Wireless clients receive the public-facing IP address of the mail server like you'd expect.  However, the connection fails. I'm not sure what's being blocked here. In the Firewall & Traffic page I have exceptions for the internal IP address of the mail server on ports 25, 143, 993, 587. I also have a deny rule to prohibit wireless clients from accessing local LAN.  No L7 rules are defined. Are these rules processed in a specific order? I was thinking they were processed top-down.   I appreciate any help ya'll can throw my way! -Brian     ... View more
