Why is it up to an ISP to block traffic?
Because the bandwidth hogged by some of the attacks that go on via specific ports slows down the entire customer base. This is especially true for things like Code Red, which if it infects just a few of your customers can result in your entire network bogging down into unusability. That's why Road Runner blocks port 80 inbound in some areas. The alternative is to cut off infected customers, and that's labor-intensive and causes some of those customers to get angry and refuse to pay instead of fixing their problem. Anyway, your ISP probably doesn't guarantee you 100% inbound bandwidth usage. Most prohibit running "servers" on non-business accounts, so being affected by these blocks implies violating terms of service. -- Shawn McMahon | Let every nation know, whether it wishes us well or ill, EIV Consulting | that we shall pay any price, bear any burden, meet any UNIX and Linux | hardship, support any friend, oppose any foe, to assure http://www.eiv.com| the survival and the success of liberty. - JFK
