Ho un problema, non so posso postare in questa sezione...

ho un router con 2 vpn attive + 1 vpn client. dietro a questo router risiede un server che necessita di connessioni sulla 5060 udp e su un range di porte sempre udp 10000-31000.

non riesco a rendere accessibili le risorse di questo server all'esterno:

ho provato ad fare:
ip nat inside source static udp 172.16.199.127 5060 interface Dialer0 5060

ma guardando sh ip nat tra ottengo:
xxx.xxx.xxx.xxx:1029 172.16.199.127:5060 62.149.193.184:5060 62.149.193.184:5060

la connessine viene negoziata sulla porta 1029 e nulla sulla 5060...

naturalmente l'acl che gestisce il traffico in sulla dialer permette la 5060...

access-list 131 remark *****************************

ho risolto....
funzionava tutto, ho riscontrato due errori miei:

1) dovevo elimanre le entry nat vecchie per vedere gli effettivi cambiament
2) provavo ad accere all'indirizzo pubblico del mio router dalla stessa rete

grazie a tutti

Come non detto, quando faccio ip nat inside source static.... i telefoni che si connettono al server in vpn sulla 5060 diventano irraggiungibili.

C'è modo di tenere la vpn e mettere il server in dmz??

nessuno sa darmi una manina?

aiutooo
