Cisco Routers :: Static IPs Behind RV220W

Picked up a pair of RV220W's for a project I'm working on.  I have several IP's available, 4 of which are assigned to/in use by a server behind the RV220W.  All 4 of these IP's are static external IPs.  How I can configure the RV220W so that requests to those 4 IP's get routed to the server.
 
Prior to purchasing this, I was under the impression what I was trying to do was called one-to-one NAT, but after reading the 'Help' document on the one-to-one NAT page, I don't think this is right.  Emphasis added below: Cisco RV220W Wireless-N Network Security Firewall Help FirewallOne-to-One NATOne-to-one NAT is a way to make systems behind a firewall and configured with private IP addresses appear to have public IP addresses.One-to-One-NAT Rule TableThis table lists the list of available One-To-One NAT rules configured by the user. Private Range Begin: start ip address in private (LAN) ip addressPublic Range Begin: start ip address in the public ip address (WAN IP), Public IP Subnet Mask: The Subnet Mask of the public IPRange Length: Range length maps one to one private address to public address up to the given range.Service: This column shows service to be accepted by LAN Host.The actions that can be taken on One-to-One-NAT rules are:(Check Box At First Column Header): Selects all the entries in the table.Add: Opens the One-To-One NAT Configuration page, to add a new entry. Edit: Opens the One-To-One NAT Configuration page, to edit the selected entry.Delete: Deletes the selected entries.
 
So according to their documentation, the server in question would need to be configured with a private IP.  Unfortunately, one of the applications I use is licensed via IP address and my understanding is that I cannot use the software with private/non-routable IP addresses.
 
Is the RV220W capable of not only securing the line (firewall, access rules, content filtering, port trigering & forwarding etc) but also doing what I was hoping to do (keeping the external IP's on the server, and routing appropriately)?
