Check And Configure Firewall Settings - Cisco Meraki MR55 Installation Manual

MR55.
1.
Attach your MR55 to power and a wired Internet connection. See the "Power the MR55" section for details.
2.
The MR55 will turn on and the LED will glow solid orange. If the unit does not require a firmware upgrade, the LED will turn either green (no clients
associated) or blue (clients associated) within thirty seconds.
* If the unit requires an upgrade, the LED will begin blinking orange until the upgrade is complete, at which point the LED will turn solid green or blue. You should
allow at least a few minutes for the firmware upgrade to complete, depending on the speed of your internet connection.
MR45/55 APs are based on the latest WiFi-6 technology. Due to this, some WLAN adapters may not be able to
list the SSID on 2.4GHz or 5GHz frequencies. We recommend updating the software driver for the wireless NIC
on your client device if the client is unable to see the configured SSIDs. Alternatively, you can disable AX
functionality for 2.4GHz band using RF profiles. If you need to disable AX in the 5GHz band, please reach out to
Meraki Support.
Check and Configure Firewall Settings
If a firewall is in place, it must allow outgoing connections on particular ports to particular IP addresses. The most current list of outbound ports and IP addresses
for your particular organization can be found here.
Assigning IP Addresses to MR55
All gateway MR55s (MR55s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP addresses can be dynamically assigned
via DHCP or statically assigned.
