Loss of DNS

Following a temporary loss of DNS server this morning, does anyone know the significance of the following entries in the logs of my Technicolor TG 582n router?

Warning May 8 10:03:56 IDS proto parser : tcp invalid urgent offset (1 of 1) : 183.230.221.35 <My IP address> 60 167 TCP 60107->59426 [S...U.] seq 2491958906 ack 0 win 0

Warning May 8 09:43:31 IDS proto parser : tcp invalid urgent offset (1 of 1) : 211.142.106.146 <My IP address> 60 47 TCP 49403->12300 [S...U.] seq 1902828489 ack 0 win 0

Warning May 8 09:36:31 IDS scan parser : tcp syn scan: 89.248.165.121 scanned at least 20 ports at <My IP address> (1 of 1) : 89.248.165.121 31.125.76.2 40 246 TCP 44327->6468 [S.....] seq 1146483660 ack 0 win 1024


One interesting point: My IP address has changed! I don't know when it changed but I had the same (unfixed!) fixed IP address for years.

 

TIA

Re: Loss of DNS

Looks like your router has been under attack, be patience as  they’ll eventually go away…
