Re: parzialmente OT Nat Portigate 50A
Non rispondermi in privato: non sono un grande esperto di reti, ed il
lista puoi trovare persone piu' brave di me...

E non conosci la rete in cui era inserito prima? Se conoscessi un nodo
di quella rete, potresti risalire a quella del Portigate, altrimenti
credo tu debba ingare TUTTE le reti...
Il mio modem e' sul 10.0.0.138 ed al ping risponde
# ping -c 1 10.0.0.138
PING 10.0.0.138 (10.0.0.138) 56(84) bytes of data.
64 bytes from 10.0.0.138: icmp_seq=1 ttl=255 time=1.13 ms

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 1.132/1.132/1.132/0.000 ms
ma se ping l'indirizzo di broadcast della rete non ottengo nessuna risposta:
allora, molto grezzamente, ho fatto:
# echo "for i in \`seq 1 254\` ; do ping -c 1 10.0.0.\$i -i 0; done" >
ping.sh && chmod +x ping.sh && /usr/bin/time ./ping.sh

C'ha messo un bel po'!
Ma guarda un po' invece che ti tira fuori nmap:

caught SIGINT signal, cleaning up
Magari limitati solo alle sottoreti private... e non a tutta Internet

Beh, divertiti! ;)
