Muchos de vosotros pensareis que con usar el \u00abip-forwarding\u00bb de BungeeCord y activar en Spigot el modo BungeeCord es suficiente seguridad para vuestra network, pero no es as\u00ed.<\/p>\n

Si saben la IP del servidor, pueden crear un BungeeCord y entrar a trav\u00e9s de el y saltar por completo el\u00a0ip-forwarding. La informaci\u00f3n siguiente trata de como proteger esto.<\/p>\n

B\u00e1sicamente, lo que permite \u00abIp-tables\u00bb es hacer que solo se pueda entrar a un servidor a trav\u00e9s de tu BungeeCord.<\/p>\n

\u00a1Atenci\u00f3n! Para realizar esto necesit\u00e1is tener un dedicado y un acceso por consola con \u00abroot\u00bb (Para m\u00e1s seguridad).<\/strong><\/p>\n

 <\/p>\n

INSTALACI\u00d3N<\/strong><\/h3>\n

Instalar Iptables es bastante sencillo:<\/p>\n

Distribuciones RedHat\/CentOS 7<\/span><\/h5>\n
sudo yum install iptables<\/pre>\n
Distribuciones Debian\/Ubuntu<\/span><\/h5>\n
sudo apt-get install iptables<\/pre>\n
 <\/p>\n
USO<\/h3>\n
Solo tienes que sustituir \u00ab$BUNGEE_IP\u00bb por la IP de tu BungeeCord y \u00ab$SERVER_PORT\u00bb por el puerto del servidor que queremos proteger.<\/p>\n
A\u00f1adir solo un puerto<\/span><\/h5>\n
iptables -I INPUT ! -s $BUNGEE_IP -p tcp --dport $SERVER_PORT -j DROP\r\n<\/pre>\n
 <\/p>\n
Aqu\u00ed se sustituye \u00ab$BUNGEE_IP\u00bb por la IP de tu BungeeCord, \u00ab$START_PORT\u00bb por el puerto inicial y \u00ab$END_PORT\u00bb por el puerto final.<\/p>\n
A\u00f1adir desde un puerto hasta otro<\/span><\/h5>\n
iptables -I INPUT ! -s $BUNGEE_IP -p tcp --dport $START_PORT:$END_PORT -j DROP<\/pre>\n
 <\/p>\n
GUARDAR IP-TABLES<\/h3>\n
Despu\u00e9s de este proceso, debes guardar lo que has hecho y para ello utiliza estos c\u00f3digos:<\/p>\n
Distribuciones RedHat<\/span><\/h5>\n
\/etc\/init.d\/iptables save<\/pre>\n
Distribuciones Debian\/Ubuntu<\/span><\/h5>\n
apt-get install iptables-persistent\r\n\/etc\/init.d\/iptables-persistent save<\/pre>\n
Distribuciones CentOS 7\/RHEL<\/span><\/h5>\n
iptables-save<\/pre>\n
 <\/p>\n
RESETEAR IP-TABLES<\/h3>\n
Para resetear Iptables es solo un comando:<\/p>\n
iptables --flush<\/pre>\n
 <\/p>\n
Espero que os sirva de ayuda para que vuestros servidores sean m\u00e1s seguros.<\/p>\n","protected":false},"excerpt":{"rendered":"
