DDos attack: Teardrop

In questi ultimi giorni sto avendo problemi con questa tipologia di attacchi Ddos, specialmente con i servizi di Playstation Network nei giochi multiplayer online, sto cercando di capire se esiste una configurazione tale da poter prevenire le continue disconnessioni quando uso questi servizi. Io usco un D6400 aggiornato all'ultimo firmware uscito e vedo che ci sono delle voci che potrebbero aiutarmi ma prima di modificare qualche parametro avrei bisogno di un aiuto competente e quindi chiedo a voi se potete aiutarmi.

Ho notato che vi è presente un servizio vpn interno al router però non sò se è utile e nel caso come configurarlo, ho visto che nella configurazione Wan c'è una voce che aiuta a prevenire gli attacchi Ddos ma non capisco se deve essere attivata oppure lo è già.

    Gentile Actarus,

     

    Benvenuto nella Community NETGEAR Italia 🙂

     

    Avrei bisogno di maggiori informazioni inerenti al suo problema.

     

    Le chiederei se questa problematica è nata dopo che ha effettuato l'aggiornamento del firmware?

     

    Inoltre, vorrei chiederle se il suo D6400 è collegato in cascata ad un modem router? In questo caso, il modem router a monte in che modalita è impostato?

     

    Saluti,

      Team NETGEARInnnazitutto Grazie per il benvenuto

       

      Innazitutto grazie per il benvenuto 🙂

      Non del tutto, diciamo che è successo anche in passato con altri firmware ma sono stati episodi veramente sporadici e tantomeno insistenti, da la sera di Venerdì invece si manifestano molto più spesso anzi quotidianamente e l'update del firmware 114 l'ho fatto l'8 marzo.

      No, non è collegato in cascata, c'è solo lui connesso al dispositivo della fibra ottica di telecom e di dispositivi connessi sono tutti cabalati prevalentemente quelli di uso assiduo.
