Rozbalit Rozbalit vše Velká odezva přes OpenVPN tunel (>10s)

tcpdump2.txt (7890 bytů)

Dobrý den, řeším již třetím dnem problém na mém routeru. Když se připojím přes OpenVPN z venku tak vše funguje normálně, ale pouze chvíli. Po připojení k VPN zapnu ping na stroj v lokální síti (skrz tunel) a přibližně tak po 100-150 paketech na chvíli vypadne spojení (viz příloha). Když VPN jela přes udp, pakety byly samozřejmě ztraceny. Přes tcp se pakety s odezvou kolem 15s vrátí zpět. Na routeru jsem spustil tcpdump a je vidět že router odesílá hodně paketů se špatným kontrolním součtem TCP a když dojde k výpadku tak i nulové délky.

Na routeru jsou síťové karty Realtek RTL8111/8168B, které původně používaly ovladač r8169. Nyní jsem zkompiloval nový modul ze stránek výrobce ale problém přetrvává.

Myslíte, že jde o hardwarový problém nebo softwarový? Nesetkal jste se někdo s něčím podobným ?

Předem děkuji za odpovědi.

Ping skrz tunel

V tomto formuláři můžete formulovat svou stížnost ohledně příspěvku. Nejprve vyberte typ akce, kterou navrhujete provést s diskusí či příspěvkem. Potom do textového pole napište důvody, proč by měli admini provést vaši žádost, problém nemusí být patrný na první pohled. Odkaz na příspěvek bude přidán automaticky.

Offtopic diskuse použijte pro diskusi mimo záběr našeho portálu (včelařství, windows), která by měla být smazána.
Duplicitní diskuse je určena pro případ, kdy uživatel odeslal svůj dotaz několikrát.
Návrh na cenzuru použijte, pokud komentář obsahuje urážky, vulgarismy nebo porušuje zákony.
Návrh na smazání komentáře je velmi neobvyklá akce používaná obvykle při nepovolené reklamě či spamu, výkřicích psychicky nemocných jedinců (ještírci) nebo pro smazání duplikátních komentářů.
Oprava formátování je žádost pro úpravu formy příspěvku, například pokud někdo píše bez odstavců nebo použije PRE pro celý komentář. Žádosti o změnu obsahu budou zamítnuty.
