One of our client (a Little Service Provider) use a 7204vxr as there
Internet Access Router, they use NAT for their clients, but recently,
the router is always suffered by High CPU Utilization, when they use the
command "show ip nat trans" , a big amount of connection with the same
src & dst ip address are found, maybe caused by RedCode or the Virus
similar, when use "clear ip nat trans *" the CPU Utilization dived down ,
My problem is how to resolve it efficiently?
Thanks in advance
