Configure RRAS with multiple public STATIC IP address

<p>I have Server 2012 Standard edition. &nbsp;I have two network cards installed. &nbsp;I have configure my server to be my router aka NAT BOX using Server 2k12 RRAS. We recently added more servers to our internal network. We needed more Public Static IP address. Currently we had one and then upgrade to 5 with Time Warner. I configure my WAN NIC card on the server with the new Static IP address from TIME WARNER. How do I add the remaining ones to RRAS. THen i can use services tab to add that static IP address with this port to that internal ip address which happens to be another server. &nbsp;</p><p>Currently when I add to the address pool tab couple my PC or servers gets kicked off the internet especially when I add the service port and the public ip address from the public ip address pool and the internal ip address and the internal port.&nbsp;</p><p></p><p>Anyhow, what i am trying achieve here is NAT the remaining public IP Address to an internal ip address. Only a certain ports such as SMTP Port, VPN port, pop3 port, HTTP port HTTPS ports. &nbsp;Can someone help me configure this on RRAS on server 2012</p>
