We have Cisco ASA 5510, it became necessary to publish port 443 outward. ASDM began to swear that it could not reserve this port. As I could find out, this is due to the fact that the ASDM itself connects to port 443.

Is it possible to change the port of the ASDM connection to the ace, what would be the opportunity to add a rule on this port?

ASDM version 6.3 (1), ASA firmware version 8.3 (1).

    To change the connection port in ASDM you need to go to

    Configuration -> Device Management -> Management Access -> ASDM / HTTPS / Telnet / SSH

    There in the Port Number enter your port. After that, when connecting to ASDM, it is required to enter the asy IP address and port through a colon (for example, 10.10.10.10:8080).

    You may also need to switch SSL VPN to another port, or turn it off, because It also occupies port 443.

    You can change the port or disable SSL VPN in Configuration -> Remote Access VPN -> Clientless SSL VPN Access -> Connection Profiles.
