SysLog
Advance Setting
For troubleshooting needs you can specify the filter log and/or
CSM log here. Check the corresponding box to enable the log
function. Then, the filter log and/or CSM log will be shown on
Draytek Syslog window.
Click Edit to open the following window. However, it is strongly
recommended to use the default settings here.
Codepage - This function is used to compare the characters
among different languages. Choose correct codepage can help the
system obtaining correct ASCII after decoding data from URL
and enhance the correctness of URL Content Filter. The default
value for this setting is ANSI 1252 Latin I. If you do not choose
any codepage, no decoding job of URL will be processed. Please
use the drop-down list to choose a codepage.
If you do not have any idea of choosing suitable codepage, please
open Syslog. From Codepage Information of Setup dialog, you
will see the recommended codepage listed on the dialog box.
Window size – It determines the size of TCP protocol (0~65535).
The more the value is, the better the performance will be.
However, if the network is not stable, small value will be proper.
Session timeout–Setting timeout for sessions can make the best
utilization of network resources. However, Queue timeout is
configured for TCP protocol only; session timeout is configured
for the data flow which matched with the firewall rule.
