==== Se abbiamo una macchina con 2 o + interfacce di rete e vogliamo usarle come un switch useremo un bridge ====
* Come rete uso uan privata di classe A 192.168.1.0/24
* Stoppo iptables:
/etc/init.d/iptables stop
* Aggiungo le regole a iptables in modo da non farmi bloccare le connessioni
iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -d 192.168.1.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -j MASQUERADE
* Salvo e avvio iptables
/etc/init.d/iptables save
/etc/init.d/iptables start
* Creo effettivamente il bridge
brctl addbr br0
brctl stp br0 off
* Ci acciungo le 2 interfaccie (o +)
brctl addif br0 eth0
brctl addif br0 eth1
* Imposto l'ip in bianco, dato che l'indirizzo delle schede non è necessario, ce ne sarà uno per entrambe.
ifconfig eth1 0 0.0.0.0
ifconfig eth0 0 0.0.0.0
* Do l'indirizzo al bridge (unione delle due interfacce)
ifconfig br0 192.168.1.82 netmask 255.255.255.0 up
echo '1' > /proc/sys/net/ipv4/ip_forward
* creo la route per il mio gateway
route add default gw 192.168.1.1
* vediamo che dice ifconfig...
ifconfig
