Mysterious DOS trace_route mail alerts was created by icarusbop
Hello:

I've suddenly started receiving a lot of email alerts (approx 1 per minute) from my router as follows:

"2015/11/05 12:28:39 -- [DOS][Block][trace_route][192.168.1.11:54773->239.255.255.250:1900][UDP][HLen=20, TLen=161]"
(multiple copies in each email)

The odd thing is - I've logged in to my network and cannot find the unit with an IP of "192.168.1.11" - this IP is not in use in my DHCP table and there are no responses to Pings to the address.

So any ideas where these are coming from?
I'd like to fic the issue rather than ignore it as it may be taking up bandwidth due to the amount of mails I'm getting.

Thanks
Ian
