Can I permit an inside host to an outside host; but instead of using outside host actual ip address; I have to use the outside host domain name?
When I configure the acl; for instance "permit ip any host domain_name.com; the router translates the domain_name.com to the actual ip address. When I do "sh access-list access_lists_name; I don't see the domain name on the acl. I see the actual ip address resolved by DNS. My vendor told me that I should use the domain name; because their IP address isn't fix.
So If now I configure the acl with the domain name; the router translates it to the actual ip address and later on the vendor change their ip address; but same domain name; will I need to reconfigure my acl ?
Regards.
