problema con 1721 - configurazione

[spcadmin]

scusatemi

sto diventando pazzo

i led sono accesi , faccio lo sh int e tutto e' in UP ma non si naviga e non lo vedo da esterno.

mi hanno dato i seguenti parametri di configurazione

TD assegnata al cliente: xxxxxx
* Subnet IP: 83.xxx.xxx.145/32
* p-t-p: 62.xx.xx.130/30
* Dlci 20
* MCR: 64 Kbit/s





vedete qualche cosa di sbagliato che non vedo io nella configurazione

Confermo mancano le regole x il nat:

interface Serial0.1 point-to-point
ip nat outside

interface FastEthernet0
ip nat inside

acl per il nat
