Ciao a tutti una domanda secca perchè se inserisco il comando:
ip nat inside source static tcp x.x.x.x 3389 x.x.x.x 3389 extendable
non telnetto piu il router sia su lan che wan?
grazie a tutti coloro mi faranno chiarezza.

Mhm...mi sembra un po' strano.
Facci vedere la config completa.

ecco la mia config p.s. sono auto didatta in materia e chiedo scusa per eventuali errori grazie

Intanto:

grazie mille tutto o.k.
posso azzardare un'altra domanda?
come puoi vedere dalla mia config ho la necessita di nattare un range di porte verso 2 indirizzi interni,come posso far fare al router tale attività con dei comandi che racchiudono piu porte? dalle note prese in rete faccio casino.grazie

Tu vuoi racchidere tutte queste righe di nat in una unica?

ip nat inside source static udp 192.168.99.101 5060 213.199.x.x 5060 extendable
ip nat inside source static udp 192.168.99.101 2727 213.199.x.x 2727 extendable
ip nat inside source static udp 192.168.99.101 2427 213.199.x.x 2427 extendable
ip nat inside source static udp 192.168.99.101 10000 213.199.x.x 10000 extendable

ip nat inside source static udp 192.168.99.101 10002 213.199.x.x 10002 extendable
ip nat inside source static udp 192.168.99.101 20000 213.199.x.x 20000 extendable
ip nat inside source static udp 192.168.99.101 20001 213.199.x.x 20001 extendable
ip nat inside source static udp 192.168.99.101 20002 213.199.x.x 20002 extendable

Se è così prova in questo modo (non assicuro nulla perchè non lo ho mai fatto):

ip nat inside source list 111 interface atm0.1

Poi crei la acl 111 dove metti tutte le regole che vuoi creare.
