Using FQDNs in ASA ACLs?

Hello,

 

We are using a ASA 520 on 9.x and I need to enable udp/123 to europe.pool.ntp.org which looks to be a cluster of IP addresses, how can I add this FQDN to the ASA to be resolved?

 

Thanks

You just need to define a DNS

You just need to direct the ASA to do lookups and define a DNS server (or servers) so the ASA knows what to use as a resolver. Follow this link.

Once you have that, then simply follow the configuration guide section on creating access-list entries.
