SYN attack

Asked by aej1973 in Networking Hardware Firewalls, Network Routers

Hello, I have a small network and have a Cisco 2620 edge router. I am getting  as SYN flood attack but unable ot detect from where it is originating. I have run my debug command and I see one like as follows:

*Apr 14 06:08:06.628:     TCP src=2577, dst=80, seq=2941387085, ack=0, win=65535
 SYN

But this does not tell me where the attack is coming from. Also, how do I prevend this from happening? Thanks for the help.
