Hi!! I have a 3.3.5 server. I have the ports open on the router and I received by console a message like the following: WorldSocket::ReadHeaderHandler(): client #IP_ADRESS# sent malformed packet (size: , cmd: ) I know it is someone trying to access with the wrong command But can I do something to avoid it? Could it be a security breach on my computer? Thank you very much. Regards.
