create ACL using Hostname

[oosama123]

hi everyone,

i need to create ACL to allow domain to enter our network , and they don't have a public IP , instead they are using Dynamicdns.

So i need to add them to our white list by using Domain name.

the problem here , i have followed all steps here :

https://supportforums.cisco.com/document/66011/using-hostnames-dns-access-lists-configuration-steps-caveats-and-troubleshooting#Step_1:_Define_DNS_server

but when i reach this command :

object network obj-hr88.cisco.com
  fqdn hr88.cisco.com

it's not recognize FQDN as a command ! i don't know why!

we have an old firewall : ASA version 8.0 (5) 27

Hi oosama123

FQDN rules for objects have been introduced with ASA 8.4(2) - this is why your command is not recognised (according to http://www.cisco.com/c/en/us/td/docs/security/asa/asa-command-reference/A-H/cmdref1/f2.html)
