Well that's a different issue. When you said you wanted to remove the messages, I assumed you knew them to be safe. That sometimes is the case. But without any context, it's impossible for anyone else to know if it's safe or not. And if you don't know, then instead of hiding the messages, you need to determine the cause. That's the point of having the warning messages.
Thanks, if the router prevents these attacks, it's good for me. So, I would like to hide these warnings without disabling any protection on my router. just removing the display of this type of messages at Syslog windows.
