The ZyWALL’s traffic throughput rate decreased after I started collecting traffic
statistics.

I can only see newer logs. Older logs are missing.
When a log reaches the maximum number of log messages, new log messages
automatically overwrite existing log messages, starting with the oldest existing log
message first.
The commands in my configuration file or shell script are not working properly.
• In a configuration file or shell script, use “#” or “!” as the first character of a
command line to have the ZyWALL treat the line as a comment.
• Your configuration files or shell scripts can use “exit” or a command line
consisting of a single “!” to have the ZyWALL exit sub command mode.
•Include write commands in your scripts. Otherwise the changes will be lost
when the ZyWALL restarts. You could use multiple write commands in a long
script.
Note: “exit” or “!'” must follow sub commands if it is to make the ZyWALL exit sub
command mode.
See Chapter 52 on page 873 for more on configuration files and shell scripts.
