Qualcuno mi sa dire come modificare questa configurazione per forwardare verso l'interno alcune porte? Oppure ancora meglio, se possibile, abilitare il protocollo upnp per lo scopo.

ecco la mia configurazione (una telecom routed con 8 indirizzi ip statici)

Ciao, il port forward lo fai con il NAT statico. Oppure hai 5 IP pubblici, usa quelli.

Paolo

come uso i 5 ip pubblici? posso associare un ip pubblico a un ip interno statico? come si fa?

Codice: Seleziona tutto

ip nat inside source static tcp IP_INTERNO PORTA_INTERNA  interface ATM0.1 PORTA_ESTERNA

ho aggiunto queste righe, ma sembra non funzionare:

ip nat inside source static udp 192.168.0.5 10000 interface ATM0.1 10000
ip nat inside source static udp 192.168.0.5 10001 interface ATM0.1 10001
ip nat inside source static udp 192.168.0.5 10002 interface ATM0.1 10002
ip nat inside source static udp 192.168.0.5 10003 interface ATM0.1 10003
ip nat inside source static udp 192.168.0.5 10004 interface ATM0.1 10004
ip nat inside source static tcp 192.168.0.5 10000 interface ATM0.1 10000
ip nat inside source static tcp 192.168.0.5 10001 interface ATM0.1 10001
ip nat inside source static tcp 192.168.0.5 10002 interface ATM0.1 10002
ip nat inside source static tcp 192.168.0.5 10003 interface ATM0.1 10003
ip nat inside source static tcp 192.168.0.5 10004 interface ATM0.1 10004

Puoi direttamente assegnare gli IP pubblici ai PC. Come gateway usare il finale 44.
Naturalmente i PC devono avere un firewall.

Paolo

P.S. Prova a levare i comandi precedenti e mettere

Naturalmente se metti gli IP pubblici sul PC non serve mettere il NAT
