Re: [Help] Syncflood attack on Belkin
I suspect that you already know this, but your only likely remedy is to buy a real router.
The synflood packets by themselves do not usually take up much bandwidth. The likely reason that your internet connection is being affected is that your brain dead Belkin router is still making NAT table entries for each incoming synflood packet (even though it has already diagnosed them as synflood packets). When the available memory for NAT table entries is used up, your internet connection is then blocked. That is why this kind of probe is called a "denial of service" attack. I had to dump a D-Link DI-LB604 router for this same kind of behavior. My current Cisco/Linksys RV082 just laughs at DDoS attacks and keeps on trucking.
