Hello all,
Stumped on this issue, we updated our firepower ftds (yes I know, firepowers, blech) and after that, all ntp services passing through it cannot remain synchronized, we have done internal->ftd->dmz, dmz->ftd->outside, internal->ftd->outside, and no matter what it fails, we use ntpd on a linux server for testing, but we have 6 different servers that fail to stay synced. Sometimes it can stay synced for a few mins, to hours, then it just constantly syncs/unsyncs. I opened a tac case, the tac had me fastpath ALL ntp traffic in->out and it didn't help, had him go over the packet captures twice and no luck, packets dont seem to be blocked and aren't going out of order so I am stumped at this point.
We are on 6.4.0.3
Any suggestions?
