hi guys,
from the central station I can ping the Async port of my remote router but i can not ping the fastethernet interface!!
any solution?

There might be several things that could cause the symptoms that you describe.
- the central station might have a route to the address of the Async port but not have a route to the FastEthernet.
- there might be an access list that permits ping to some addresses but not to other addresses.
- is there some possibility that the remote FastEthernet might not be up/up?
- there might be issues on the remote controlling what traffic is sent over the async interface.
If you provide details like the configuration of the router we would be better able to help you.

Thanks for posting the router configs. They are quite helpful in understanding your problem. Your origional post indicates that you can not ping the remote FastEthernet. The config shows that there are 5 FastEthernet interfaces and 4 of them are shutdown and the last one has no IP address. You certainly can not ping an interface that is shut down nor an interface that has no IP address.
