Hello All,

I have a connection to AT&T and I have been seeing a ton of 12.0.0.0 host trying to connect to several UDP & TCP ports such as 135,137,139, 445. And netbios-ns. The firewall is blocking all of this traffic, but log entries are driving me insane. Should I have ATT block these ports on the Serial or is there another way to do this on the PIX without seeing all the dropped traffic?

Thanks,

DF

Block this IP at the perimeter or aggregate router upstream from the PIX. That will stop the syslog flood.
