Accelerator

A simple game accelerator

build:
apt-get libpcap-dev
yum install libpcap-devel

On Windows, must enable Windows firewall for filter
outbound packets, include RST about TCP(not need rule).
add rule ICMPv4 destination unreachable(type 3, code 3),
add rule ICMPv6 destination unreachable(type 1, code 4),

On Linux, must use iptables/ip6tables for filter outbound
packets, include RST about TCP and ICMPv4/ICMPv6.

iptables -A OUTPUT -p tcp -m tcp --tcp-flags RST RST -j DROP
iptables -A OUTPUT -p icmp -m icmp --icmp-type 3 -j DROP
ip6tables -A OUTPUT -p tcp -m tcp --tcp-flags RST RST -j DROP
ip6tables -A OUTPUT -p icmpv6 -m icmpv6 --icmpv6-type 1 -j DROP

recommend enable TCP BBR for better effect(IPv4&IPv6)

sudo sysctl -w net.ipv4.tcp_congestion_control=bbr
