I have configured ADSL on my Cisco 1841 router. Intern is working fine. But as i give the below command on router, i lose my telnet connectivity via public ip address. Any clue?
ip nat inside source list 1 interface dialer 1 overload
Can you give us more detail of how the router is configured? In particular does access list contain a permit any statement? I have seen situations where it seems that address translation with a list with permit any does impact telnet access on the public interface. If your access list 1 does contain permit any then I suggest that you re-write the access list so that it does not permit any.
