is correct. Before confirmation, packets are forwarded by App Patrol with no action taken. The number
of packets inspected before confirmation varies by signature.
Note: The Zyxel Device allows the first eight packets to go through the security policy,
regardless of the application patrol policy for the application. The Zyxel Device
examines these first eight packets to identify the application.
The second approach is called service ports. The Zyxel Device uses only OSI level-4 information, such as
ports, to identify what application is using the connection. This approach is available in case the Zyxel
Device identifies a lot of "false positives" for a particular application.
Custom Ports for SIP and the SIP ALG
Configuring application patrol to use custom port numbers for SIP traffic also configures the SIP ALG to
use the same port numbers for SIP traffic. Likewise, configuring the SIP ALG to use custom port numbers
for SIP traffic also configures application patrol to use the same port numbers for SIP traffic.
