1. A method comprising:
receiving, by a wireless access point, a first packet for an application;
generating, by the wireless access point and based on the application of the first packet, an entry in an application server address cache specifying an address of an application server that hosts the application and a forwarding action to send traffic for the application to the application server via a local breakout path instead of tunneling the traffic to a gateway connected to the application server;
receiving, by the wireless access point, a second packet for the application;
configuring, by the wireless access point and in response to determining that the second packet matches the entry in the application server address cache, a packet flow for the application including the forwarding action to send traffic associated with the packet flow to the application server via the local breakout path instead of tunneling the traffic to a gateway connected to the application server; and
sending, by the wireless access point and based on the forwarding action, a subsequent packet that is subsequent to the second packet and associated with the packet flow to the application server via the local breakout path.
