[ Scanning] drop rate-1 exceeded.

Hi, were experiencing an issue where our speeds are slow and were getting the folloing in our log files... I assume were under some sort of attack, but im not sure what to do about it.

No matching connection for ICMP error message: icmp src Outside:203.171.50.11 dst identity:203.161.94.62 (type 4, code 0) on Outside interface. Original IP payload: tcp src EXTERNALIP/51707 dst 10.1.1.187/80.

and

and

Duplicate TCP SYN from Outside:216.218.206.80/35753 to Outside:203.153.238.95/443 with different initial sequence number
