Hi all. I have a cisco asa 5510 which i could not telnet to the inside interface. I have enabled "telnet 172.20.0.0 255.255.0.0 inside" and "passwd password" commands but it could not work. Secondly i would like to know why i could ping my external interface from internet even though my access list did not specifically allow it. Pls advise what is missing, thks in advance.
