Configuration Firewall - DoS Attack: SYN Flood


Bonjour a tous,



J ai récemment migre de Scarlet vers Voo.

Je perds régulièrement la connexion internet alors que cela ne m arrivait jamais auparavant.

Je suis obligé de redémarrer les équipements pour que cela reprennent.

J ai compris que cela provient d attaques répétitives...



Est-ce que les ingénieurs IP de l equipe Voo sont au courant et savent bloquer ces attaques dans leur propres architecture firewall avant même que mon routeur ne sature?



Je joins les logs.



Par avance merci,

Benja.

Bonsoir,

Vous pouvez essayer de forcer le changement d'IP de votre modem en le coupant durant la nuit.
Regardez l'IP WAN avant et après pour vérifiez si elle a changée.

Vous avez peut-être hérité d'une mauvaise IP ... 🤔
C est reporter le problème sur un autre client, et ca ne permet pas d éradiquer les soucis sur le long terme.

J aurais prefere que l on configure les firewall cisco dans les regles de l art...

Si j en crois cet article, le probleme est connu et une solution existe... une config correcte. ;)

Il faudrait d'abord voir si vous avez une IP publique ou privé : privée = 10.xxx.xxx.xxx
Au niveau pare-feu, cela change beaucoup évidemment !

Je n'ai aucune idée si c'est du Cisco ou autre chez VOO.
Chez nous ce n'est pas Cisco, uniquement Cisco pour les Switchs.

Hello
En IP privée, il n’est pas possible de subir des attaques de ce genre ...
une IP externe ne pourrait pas atteindre directement sa connexion...

@Nibja
Verifiez plutôt la configuration du pare feu de votre routeur, probablement que vous êtes trop « visible » sur internet ou autres activités comme jeu en ligne etc...

Votre IP chez voo ne change pas très souvent , bien que dynamique, elle est semi fixe en réalité, chez le autres fai elle change toutes les x heures ... moi j’ai la même IP depuis plus de 3 ans .

Vous pouvez changer d’IP publique en modifiant simplement la MAC adresse WAN de votre routeur personnel car les logs proviennent probablement de la ?

Bonjour @Nibja ,

Il serait peut-être intéressant de placer votre modem en mode routeur durant quelques heures, afin d’être certain que les déconnexions ou lenteurs sont bien
dues à ces attaques.
Ensuite, vérifier si votre routeur permet de modifier la Mac adresse WAN, c’est le moyen le plus rapide pour changer d’IP.

Si vous n’arrivez à aucune de ces solutions, je remonterai l’information au service réseau la semaine prochaine
Je vois de bonnes idées sur ce forum...

J ai acheté un Orbi de chez Netgear parce que le wifi du Technicolor est pourri par rapport a la bbox...

Je vais tout de même essaye la solution proposée et de le rebasculer en mode routeur.

Mais cela ne me semble pas logique.
Ce n est pas une solution viable de faire de tel chipotage..

Honnêtement... 3 ans a payer 39Euros chez scarlet... et maintenant que je paie plus cher, je suis plus souvent deconnecté.

Je pense rebasculer chez eux.
Certes la TV est plus belle chez Voo, mais les 50Mbit s de scarlet sont emplement suffisant pour l usage que j ai Netflix qui m apporte la qualité TV souhaitee.
Sans parler de votre box evasion qui est super complexe!

Bref... vous avez encore a apprendre de vos concurrents je pense...
Chez Scarlet, vous n'êtes pas limité par un quota de download ?
Si oui, vous devez certainement faire attention à l'utilisation de Netflix, surtout en HD 😙
500Go...
Jamais depasse.

Pourtant c est pas la config qui manque ici.
NAS, Camera IP, TV 4k, Xbox, smartphone, enceinte connectee,...
Bref, ce n est pas un argument de vente.
Non, juste une question ... loool
Moi je dépasse, donc Scarlet n'est déjà pas pour moi 😋

Mais bon, tous ces appareils, si vous ne les consultez pas depuis l'extérieur ne prennent pas du quota 🤓
Il faut vraiment aller sur internet pour consommer.

Il est clair que si VOO ne convient pas, il ne faut pas rester 😉
Une petite question : tous les ports attaqués ne correspondent-ils à ceux utilisé par vos jeux ?
Ce ne sont pas des ports classiques 🤔
Si oui, il n'y aurait pas quelqu'un qui voudrait vous empêcher de faire de bon score ?

Personnellement, je ne penses vraiment pas que ce soit lié à VOO, mais plutôt à l'IP ... alors on vous a donné des solutions 😙
Peut-être un apprenti hacker qui fait ses armes ?
Une IP qui aurait été hackée dans le passé ?

@DDA
Une attaque « syn flood « se porte sur de multiples ports TCP consécutifs ou aléatoires, cela a pour but de saturer le routeur par des centaines de requêtes de connexion et demandes ACK en suspend et donc ça fait ramer ou parfois même planter la connexion ... c’est une des nombreuses méthodes d’attaques par deni de services donc .

la plupart des routeurs évolués peuvent détecter et se prémunir correctement de ce genre de choses malveillantes mais je pense que c’est probablement lié à une activité particulière sur internet du client également ...
Alors que faites vous exactement sur internet qui pourrait engendrer des attaques chez vous ?

Il semble que l’attaque vienne des Pays Bas ...

Je ne vois pas pourquoi il ne laisse pas le Technicolor en routeur ...
ce netgear orbi peut probablement être configuré en mode point d’accès pour le wifi ...

@Nibja C’est pour ça que j’ai indiqué durant quelques heures. Le tout étant de s’assurer qu’il n’y avait aucun autre souci de connexion et que seules ces attaques étaient la raison de votre souci de connexion.


Avez-vous pu faire le test ? Plus aucune attaque et une connexion parfaite en repassant en mode routeur ?
Oui j ai essaye... mais j ai déjà fait le fallback. Le wifi ne porte pas assez loin et je ne sais plus faire de VPN.

Je confirme que c est juste les attaques.
Meme quand le modem est en mode bridge, je n ai aucun problème en temps normal sauf quand je reçois ces attaques...

Je le remarque vite car les logs me sont envoyés par mail quand ils atteignent la limite du buffer.
J en reçois alors un par minute, la connexion ralentit et puis le point d exclamation en symbole apparait sur mon gsm.

Je n ai pas fait de lien avec une utilisation d un device en particulier.
Celles ci se produisent même quand il n y a personne a la maison...

@Nibja : j’ai remonté l’information au service IP chez nous. Dès que j’ai une réponse, je reviens vers vous
