I've just received an e-mail apparently from myself (i.e. my own e-mail address) with the subject :
'NETGEAR *Security Alert* [3d:28:9d]'
and the contents :
TCP Packet - Source:**.***.***.**,**** Destination:**.***.*.***,**** - [DOS]
(I've replaced the IP Adddress's numbers with '*'s as this is a public forum)
As I've not posted this how has it occurred and does anyone know if this is anything I should be concerned about ?
It suggests that you have the Netgear set up to email you security log entries, John. It's perfectly normal, and is just telling you that a port has been scanned and the firewall has done its job. :)
Thanks Rik for your very prompt post, I can sleep easy tonight then. :)
Yes, the Netgear is watching over you. :)
You might find that you get a lot of emails from the router, although it depends what kind of "attacks" you have set to receive alerts about. Most of them, I would say, are completely normal, and it's just the firewall doing it's job, so you might even want to switch off email alters altogether. :)
Thanks Sebby, I've had the router nearly 12 months now though and this is the first e-mail from it that I've received.
DOS attacks are rare (hopefully) so that's probably why. If you have a look in the router settings, you'll probably find you've only got it set to warn you about these. The firewall will certainly be stopping a lot of other things. :)
I have mine set up to send logs to my email...........but it sends 2 copies each time ??? ???
stupid thing ;D ;D
Which email client do you use? Could it be a dodgy rule you've created?
