L’IP forwarding<\/span><\/strong> est la fonction de routage sous Linux<\/a><\/span><\/strong> qui permet d’autoriser la transition des paquets<\/strong> entre les diff\u00e9rentes interfaces.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Activation non permanente :<\/strong><\/p>\n\n\n\n

<\/div>\n\n\n\n
sysctl -w net.ipv4.ip_forward=1<\/code><\/pre>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
<\/div>\n\n\n\n
Activation permanente :<\/strong><\/p>\n\n\n\n
<\/div>\n\n\n\n
sed -i 's\/#net.ipv4.ip_forward=1\/net.ipv4.ip_forward=1\/' \/etc\/sysctl.conf<\/code><\/pre>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
<\/div>\n\n\n\n
Une autre m\u00e9thode<\/strong> consiste simplement \u00e0 modifier la ligne<\/strong> suivante pr\u00e9sente dans \/etc\/sysctl.conf<\/strong> :<\/p>\n\n\n\n
<\/div>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
<\/div>\n\n\n\n
Pour finir, nous utilisons la commande suivante afin de valider les changements<\/strong> :<\/p>\n\n\n\n
<\/div>\n\n\n\n
sysctl -p \/etc\/sysctl.conf<\/code><\/pre>\n\n\n\n

V\u00e9rification<\/h2>\n\n\n\n
<\/div>\n\n\n\n
Nous allons \u00e0 pr\u00e9sent v\u00e9rifier l’activation<\/strong> de cette fonction !<\/p>\n\n\n\n
<\/div>\n\n\n\n
sysctl net.ipv4.ip_forward<\/code><\/pre>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n
<\/div>\n\n\n\n
Nous pouvons aussi v\u00e9rifier ceci de cette mani\u00e8re :<\/p>\n\n\n\n
<\/div>\n\n\n\n
