Hi
We are getting DDOS attack again, tcp intercept doesnt help anymore.
Setup
INTERNET-----------------Internet_router---------ASA_firewall----------------Layer3_SW-------------LAN
Internet_Router = 2800
ASA Firewall = 5520
Layer3_SW = 4500
Source are different IP so blocking with ip not possible.
Any experience input would be appreciated.
Thanks

I see this is a day late, but for future reference you can generally contact your ISP and they can block the excess traffic for you. I contacted my ISP for their "emergency support" phone numbers and they verified that they could stop the traffic. You may want to look into that.
HTH,

Usually all hands-on-deck and involve all vendors... You need to be on the phone with these people.. Public forums is not the right avenue to obtain this kind of help where a lot of confidential information needs to be discussed.
