While I haven't had a chance to try and reproduce this on my 675 running CBOS 2.4.2, I do have a filter put in place that blocks access to port 80 on the modem only. You might try using the 'set filter' command that's part of CBOS. Placing a filter on a IP that is dynamic tends to be a pain, but, it will at least keep your modem from crashing. -Sam On Mon, 6 Aug 2001, JAX wrote:
Hi Geo . Thanx for the advice but it's still crashing. I even changed the web port to 81 , they say it's helping but it did not help me .

Seems their routers have been crashing. We traced this back to the code red worm. For some reason even with web disabled on these routers port 80 remains open. Simply running a port scan and cutting off the connection is enough to crash the router. Locks up solid. I also found a solution, by doing a set web remote ipaddress where ipaddress is one of their internal IP's you can prevent outside addresses from being able to crash the router. Just a heads up guys, if you are seeing 678's crashing, give it a try,it'sworking here. Geo.
