configuring ntp server

[waelgazlane]

Hi

please any one could support me to configure the NTP server on my Network, i am using cisco router 2911 and an ASA 5520 firewall,  i already install the net time service on my server in the office internet based zone but when i am trying to do the symchronizing it fails ?

is your NTP server behind the firewall ??

if it is behind the inside interface of the firewall you can run this command:

ntp server sourece inside

To verify you can run:

show ntp assoc

show ntp status

hope this helps.

thank you Sebastian

I am using NET TIME client behind the inside firewall( office internet zone

)  interface and linking it to a loocal time server on the internet ,

what should i configure on my firewall the inside client server ip address or the server itself on the internet ip address ?

then should i do the same on my cisco router before the firewall  ?

then any access lisst must be there on the router or ASA to allwo the inside client to get the ntp port 123 update from internet local time server .
