Turn protection on against syn attacks?

Answer 1

Open Registry Editor (the easiest way is through run command and type regedit) Find this System key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TcpIp\Parameterand create new DWORD Value (right click with mouse) named SynAttackProtect set the value data to 2

Create few more DWORD Values in the same System key: Value name: TcpMaxPortsExhausted

Value data: 5 Value name: TcpMaxHalfOpen

Value data: 500 Value name: TcpMaxHalfOpenRetried

Value data: 400 Still the same System key and create another DWORD Values: (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TcpIp\Parameter)Value name: TcpMaxConnectResponseRetransmissions

Value data: 2 Value name: TcpMaxDataRetransmissions

Value data: 2 Value name: EnablePMTUDiscovery

Value data: 0 Value name: KeepAliveTime

Value data: 300000 Find this System key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parametersand create new DWORD Value named NoNameReleaseOnDemand set the value data to 1

Set all the values correctly for maximum protection!
