Hi,
I have cisco asa firewall.
If my current connection reach 250k my network will go down.
Any method to avoid this issue from happen?
How to find the root cause?
In my case happens during attacks.
I use cisco ASDM to see connections or show connections using CLI.
I use these tools in order to find repeated entries.
Sometimes I foud a lot of connections from a single IP.
In others cases I found a lot of connections from many IPs destinated to the same port.
In this case I use ACL to block unwanted traffic.
Enable also IP audit feature in order to block some well know attacks.
Regards.
