Nekdo me "napada", kaj naj naredim?

tukaj je moj delni izpisek izpisek iz routerja (Level One FBR-1405TX Broadband Router)

problem je to da se to dogaja skoraj cel dan, in mi zelo upočasnuje internet in prekinja povezavo, s tem da se občasno pojavi tudi UDP FLOOD. Pa me zanima, če je kaj kar lahko naredim porti temu, ali naj grem kar telamchu težit da mi IP zamenja?.


PS. če je slučajno pomembno
***.***.***.*** - IP ki preko katerega se poveže router na net (tisti, ki mi ga je določil telemach)
xxx.xxx.xxx.xx -IP, ki ga dodeli router mojemu računalniku.
