All the warning messages will be sent to syslog client after you enable the
syslog function. The administrator can setup the syslog client in the

Syslog Setup

by using Web Configurator. Thus, the administrator can

DrayTek Sylsog daemon. The format for this kind of the warning messages
is similar to those in

except for the preamble keyword

“DoS”, followed by a name to indicate what kind of attacks is detected.
