hi this is the website I have been looking at:
i was advised but given as an example the following address: 188.8.131.52 in order to sync via my asa5505 which is now successful but now I wish to configure for authentication as below:
- ive configured the following via my asa5505 asdm ver 7.1 and ive currently added the following but it shows that ntp has changed from synchronized to now unsynchronized.
- interface: outside
- preferred - yes
- key: no 1
- key value: 23 for example
- trusted key: yes
asa config shows:
ntp authentication-key 1 md5
ntp trusted-key 1ntp server 184.108.40.206 key 1 source outside prefer
my asa now shows: "outside: authentication failed for packet from 220.127.116.11
question 1. how do I resolve my issue ?
