Restrict access by ddns on firewall

I have a webserver with an external ip behind a firewall but I don't want everybody to have access on it.  I am thinking of setting up ddns on the site that I would allow access to then I will restrict access based on these ddns on the firewall.  Seems perfect but when I put these policies in, the firewall does not detect those ddns address but I can ping it.  The policy is

xyz.domain.com (untrust)       x.x.x.x (external true ip - trust)        http (service)


If I change the untrust to any, it works fine.  If I put this ddns address in, the policy greys out and it searches very slow.

My firewall is a netscreen ssg5

Ping uses ICMP not HTTP so you would need to block ICMP requests as well I believe.

You are not getting my point.  I am trying to allow access from certain ddns addresses.

The problem is the dns setting on the firewall was pointed to the trusted interface instead of untrusted interface.  Working good now.
