This is the first trade publication I've seen that's covered some of the issues with ISPs blocking or not blocking ports. Port blocking last resort in fight against virus Long term problems can be caused by port blocking by Paul Brislen and James Niccolai, Auckland and San Francisco http://computerworld.co.nz/webhome.nsf/UNID/BEC6DE12EC6AE16ECC256D8000192BF7!opendocument "While some end users are calling for ISPs to block certain ports relating to the Microsoft exploit as reported yesterday (Feared RPC worm starts to spread), most ISPs are reluctant to do so."
Just a note that my manager Anand Lal is quoted in the article, he's said that the quotes attributed to him are not correct. We have put some port 135 blocks in however, probably only for a short amount of time. I've been looking at out traffic graphs and trying to decide if traffic really is down 10-15% over the last 24 hours or it's just my imagination. -- Simon Lyall. | Newsmaster | Work: simon.lyall () ihug co nz Senior Network/System Admin | Postmaster | Home: simon () darkmere gen nz Ihug Ltd, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz
