Apr 16, 2020
- Cisco ASA 5500-X Series Firewalls
Known Affected Releases
Symptom: When using the ping tcp feature, if the destination of the ping is translated by the ASA the response (TCP reset, TCP syn-ack, etc) is not displayed in the ping tcp CLI results. Only a "?" is shown the to the user (instead the correct code should be displayed "R" or "!"). Example: ASA5505# ping tcp dmz 192.168.1.2 21 repeat 1 source 188.8.131.52 1234 Type escape sequence to abort. Sending 1 TCP SYN requests to 1192.168.1.2 port 21 from 184.108.40.206 starting port 1234, timeout is 2 seconds: ? Success rate is 0 percent (0/1) ASA5505# Conditions: The ping tcp command must be used, and the destination of the TCP ping must be translated by the ASA.
