Els prefixos de xarxa privada són:        -  (10/8 prefix)      -  (172.16/12 prefix)     - (192.168/16 prefix)


podria ser que el proveïdor bloqueja port 22, per què no proves un altre?

fora bo que ens diguis de quin proveïdor es tracta i així ens animarem
a posar-lo en les nostres whitelists o blacklists personals
