We are having an issue with our ASA Firewall in that we are just getting hammered with IP's from CHINA.

They are hitting an invalid UDP/0 port, so it is dropping the packet.

So no rule I can put in will help.

I would like to put up a router or L3 switch where I can block traffic by IP address and the allow everything else,

You can block IP addresses with the ASA, but if there is that much traffic, you may need an actual IPS appliance to get enough horsepower to handle the ACLs.

UDP/0 is not a valid port so that ASA is dropping automatically |
