Remote management via ASDM/HTTPS on the Outside interface of the ASS5505 is configured and working over the Internet and is restricted to only a few host IP addresses. Access tried from any other Internet IP address does not work. However, when running a port scan from ANY Internet IP address, the ASA shows port 443 open. We have the same remote access configured for Telnet and SSH but those ports do NOT show open in a scan. How can I prevent the ASA from showing port 443 as open?
I have this problem too.
