Blocking specific applications not listed under Layer 7 firewall rules

MX Security Appliances and MR Access Points can block clients from accessing specific applications using Layer 7 firewall rules. Dashboard lists the most popular applications within each predefined category, but there might be a specific application the network administrator needs to block that is not listed. Consider the example below, for an administrator who would like to block access to the game League of Legends


Note that League of Legends is currently not listed under the Gaming category, but it can be blocked by following the steps below. 

  1. Identify public IP addresses and URLs used by the application's servers
  2. Configure a Layer 3 rule that blocks outbound connections to the application's servers
  3. Create a Layer 7 rule that blocks the URLs used by the application

Some services, such as Amazon Video, may be included in the traffic shaping applications list but not included in the layer 7 firewall application list. When blocked, these services fail over to a content distribution network (CDN) that may be shared by many content services. Meraki makes every effort to identify services from CDNs, however, in some cases, the traffic is not distinguishable from other services hosted on the CDN. In cases like these, we recommend that the application is limited to extremely minimal bandwidth usage instead of attempting to block the traffic entirely.

Identify Public IP Addresses

As of this writing, League of Legends uses the following subnets and URLs:

  • IP Addresses










  • URLs

    • pvp.net

    • leagueoflegends.com

Create a Layer 3 Firewall Rule for IPs

Navigate to Security Appliance/Wireless > Configure > Firewall & traffic shaping and select “Add a layer 3 firewall rule” for the SSID(s) you would like to block League of Legends on. Deny the subnets listed as shown below. The Layer 3 rules will block wireless clients from accessing any of the servers hosting League of Legends on these subnets:

Create a Layer 7 Rule for URLs

Navigate to Security Appliance/Wireless > Configure > Firewall & traffic shaping and Add a layer 7 firewall rule for the SSID(s) you would like to block League of Legends on. Deny the listed URLs as shown below. The Layer 7 rules will block wireless clients on that SSID from connecting to pvp.net and leagueoflegends.com.
