la cosa strana è che aggiungendo a mano (ip addr add 192.168.10.253 dev
eth1),
quindi configurando un altro ip pub sulla eth1 va tutto,
ma al riavvio perdo la configurazione della eth1

come faccio a rendere permanente il comando ip addr add 192.168.10.253 dev
eth1
che fa si che la int pubblica del firewall sia sia 192.168.10.222 che
192.168.10.253 ?
