Actually the question mark is fraudulent. My gateway/firewall machine has been under what appears to be a DDOS attack. A persistent, continuous attack from several system directed at UDP port 16252. It appears to be related to a CISCO RTR/SAA attack. What I am interested in knowing if anyone else has experienced a similar attack? The only thing I can think may have triggered this was a report to a net administrator that his system might have been compromised. A few hours later this seeming attack started. No good deed goes unpunished. Before I retired I did some security work for an employer. You would think I would've learned about sending email alerts to admins of compromised systems. Retire and a few years later you finds yourself violating the best practices. I will call the guy tomorrow. Feeling stupid. dlg
