    Hello guys,
    I have a MT RB450G, IPSec tunnel is set up on it. thus aside from regular internal internet usage, vpn connection comes on the router.
    But lately I noticed sometimes loading a site takes like forever, checked with my ISP and I was informed everything was fine, checked my AP for unknown device and knocked them off by MAC.
    In quest for a solution, I connected the ISP cable directly to my machine on which I have Kaspersky Internet Security and blaaaah! I get this info:
    THE NETWORK ATTACK DoS.Generic.SYNFlood has been blocked.
    TCP from 100.43.131.109 to port 8080
    The attacking computer has not been blocked: its address is possibly been spoofed.
    The application kept dropping this message/alert with different IP addresses. I quickly check up my bandwidth monitoring page and discovered that usage graph dropped by more than 60% thus releasing my bandwidth.
    I really need help on how block off spoofing to my network , as I have been experiencing DOS a lot.
    Please help!!!

    Talk to your ISP about it.
