url/fqdn/application based nat

 

Hi All,

Few urls and application are changes their ip address frequently, we dont have any information of that ip pool.

Can we configure nat in that wat where we dont need any destination ip address. Like when my users will try to access xyz.com and dns will resolve the destination ip addresses.nat or acls will be work on based on fqdn/urls.

 

Please share your solutions for this. Thanks in advance.

 

Regards,

Sumit

You can use FQDNs in access

You can use FQDNs in access-list entries (ACEs).  Reference.

NAT configurations must reference IP addresses (or objects/groups that are comprised of host(s), network(s) or address ranges). Reference.
