Answer 1

Hi
As checked on the firewall there is no port opened for NTP ie 123
From yesterday evening we are observing strange behaviour on the firewall inside interface.
we have configured prtg tool ie snmp traps for firewall.
For every 3 to 4 hours we receive  some alert from prtg tool during  that time ping to the inside interface drops
as observed the drop is for only for 70 to 80 sec and after that time ping is normal.
during that we have observed the logs which is defined above.
