II.
1.
- Dans les machines de S1 (table de routage) :
172.16.2.0/24 172.16.1.254
2.
Ajouter ce script dans la configuration de la passerelle :
ip addr add 127.0.0.1/8 dev lo0
ip addr add 172.16.1.254/24 dev eth0
ip addr add 172.16.2.254/24 dev eth1
iptables -t nat -A POSTROUTING -o eth1 -j SNAT --to-source 172.16.2.254
rpcbind
inetd
-> Avec ça, si une machine du S2 renvoie une information à la passerelle, on modifie l'adresse source par l'adresse de la passerelle pour que la réponse puisse arriver à la machine de destination.
III.
S3 ne peut pas ping S1, mais peut ping S2, je ne comprends pas.
