We have two identical ASA 5540s on our Border.
If we try to connect to a host protected by one of the ASA's on a port that is not permitted for this host, this results in a brief connection; the connection is then immediately closed- see below:
...$ telnet host.domain.edu 24
Connected to host.domain.edu.
Escape character is '^]'.
Connection closed by foreign host.
If we move the routing for this same host to the other ASA -which has the same rules and settings as the first ASA- we do not get this result; no connection is opened.
We can't figure out what is causing this.
Anyone else seen anything like this?
