Accessing Public IP Address (static nat) from inside the network

I have a static NAT configured on my Cisco 2801 Router.  This NAT works fine from the outside, but from inside the network I can't access the application via the public IP which is what I want to do.  Is there some type of policy NAT or something I can configure to allow me to access the the Public IP internally?  Thanks.

In Cisco land this is called 'hairpin NAT'. It's implementation it depends on your specific IOS version, but you should be able to do it on pretty much any version running on a 2801.

In Cisco's opinion, you should have a public IP for the server (a waste), or split-DNS (a nightmare) if you host a public server. Amazing how simple tasks for a Linksys become issues with a Cisco... :)

An other solution, is to create a different DNS name for this host in your inside-network.

In this case, your DNS will reply with the inside IP address from your inside network.
An other solution, if you have a few hosts, is to create a hosts record, for this service on every workstation.

Split DNS is really easy to implement on bind9 DNS sever
