I work for an isp and we have a router that is getting killed by the nachi virus. i have blocked all the ports they say to except netbios cause we use it and icmp. the router that is getting hit is one in the middle and not an area router. here is the running config, anything else needed would be great. i know i need to black icmp but i am not sure where, as in in or out and on which router, the one that is getting hit or the two its connected too. any helps would be great, then i could leave and enjoy labor day.
thanks
mike
