incoming port 666


Recommended Posts

Norton Internet Security has been reporting incoming UDP requests on port 666. What exactly is this port used for? For the time being I have pressed block each time, but it seems to be happening about 3 times per day. It also says DOOM after port 666. As far as I know, there is no need for incoming requests on that particular port, but I still don't know what it is used for. I would also like to know if it might be a good idea to block that port on my router. Thanks for the help in advance!

Huh?? Your behind a router - every dsl/cable router I have ever seen BLOCKS all inbound ports, unless it is a reply to something - and since UDP, that does not make sense?? Are you in the DMZ of your router? Or did setup a forward for a range of ports that include this? What IP address is it coming from, maybe its something inside your network?
