il mio router è un Soho91, il mio problema è di configurare il router in modo da fare da interfaccia tra la rete aziendale e il gateway internet.
provo a spiegare la situazione:
rete aziendale indirizzi ip 192.168.1.XXX
router cisco, porta Eth0 192.168.1.1
porta Eth1 172.10.3.100
Indirizzo antenna per Adsl 172.10.3.5
con la configurazione che posto sotto, dal pc con ip 192.168.1.20 faccio il ping alla eth1 correttamente, mentre se faccio il ping a 172.10.3.5 ottengo "Richiesta Scaduta".
allego un pò di informazioni:
