有甚麼解決方法?
router 型號是planex brl-04ur, 用bb100上網
用緊nod32

jackli 發表於 2008-12-13 11:15

用部勁機黎做router:naug: 4GB ram

t1174-3 發表於 2008-12-13 11:43

bb100,可能可以 try try 轉 router wan的 mac address (clone 第2 個 mac addr) 來 force 轉 ip

人地應該成個subnet  咁做UDP Attack
或者client 機有software 「裡應外合」 [/quote]
如果成個 subnet, 只有 report hkbn 了.

要轉 ip, 就是想試是不是有 malware 裡應外合

jackli 發表於 2008-12-13 12:05

好多彊屍:naug: , 根本就只可以report hkbn,
不過其實, hkbn的server都會好大loading..:xd:

HKBN can do nothing indeed
除非開恆firewall block 所有UDP Packet :xd: [/quote]

:agree:  hkbn, 採你都傻 :redface: , 除非好過份,
不過正常屋企, 都無咩可能同時間hold 百萬條連線:naug: , 又唔係做server....

HKBN唔係有權於任何時候禁止某用戶上網?

即是個人沒有方法? 要打給hkbn 換ip 嗎?
己用nod32 and ad-aware掃過毒和木馬

1.to change your router's wan side ip, change its mac address, then hkbn would give you another wan ip.
2.all free good stuff, try!

有 log 迷即係 block 咗囉 :haha:

vicor5137 發表於 2008-12-14 11:26

THX 各位, 問題找到啦, 是我弟部機install 太多不知名software,online game program,  format 左不用就沒有問題.
p.s.個router 沒有16榭樓個function, block ip 不work , 一小時內多於20pages record, 在router release ip and renew 都是同樣get same ip, 是mac adress change 左 take 左另外ip,but 仍然被attack.

除非你炸o左對方 pc, 佢 attack 你冇得 stop
只可以靠 router firewall drop 佢 packet
你隻 router 只要 turn on SPI Mode default 應該幫你 drop 咗 ....... 如果唔係點會有 log 睇 :haha:
