WebIptables rules,-a and -g This program sends packets via raw socket. In FakeTCP mode, Linux kernel TCP packet processing has to be blocked by a iptables rule on both sides, otherwise the kernel will automatically send RST for an unrecongized TCP packet and you will sustain from stability / peformance problems. WebStream sockets provide the most reliable connection. Datagrams and raw sockets are unreliable because packets can be discarded or duplicated during transmission. This characteristic might be acceptable if the application does not require reliability or if the application implements reliability beyond the socket interface. Performance
