I'd like to make a 4507 the NTP server for our organization. I figure it has the least amount of downtime of any server I would run NTP services on, doesn't get patched frequently like a traditional file server(so less downtime), and I don't plan on replacing it in the forseeable future.
I've put in a basic config, but it doesn't seem to be working(or at least my linux servers don't see it as an NTP server).
Here are the pertinant bits from the config:
interface Loopback99<br/> description ntp server address<br/> ip address 192.168.199.99 255.255.255.255<br/><br/>.....<br/><br/>
ntp source Loopback99<br/>ntp server 18.104.22.168<br/>
The NTP server command points to a stratum one server at Penn State University. I have the following config in my ASA to allow the loopback to poll the remote NTP server:
access-list Inside_access_in extended permit udp host 192.168.199.99 any eq ntp
nat (Inside) 1 192.168.199.99 255.255.255.255
Any thoughts on what I'm missing or have configured incorrectly?
