Using WAN Alias IP for specific hosts in LAN - getting confused.

Question

Hi, 
 I, like many of you I am sure, have a range of public IP addresses set up on my wan port. 
 Routing from outside in is fine with NAT, I have servers running fine on them. 
 What I am having trouble with though is how to configure making a internal server, use one of the external IP numbers. 
 I thought I might have needed the patch from Sophos which is installed, but I just cant get my head round how to set it up. 
 Could someone assist with the process, I am only getting more and more confused looking at other posts. 
 Thanks, 
 Richard.

Richard, 
 once you have installed the Sophos patch and created the Alias from System > Network > Interface, create the additional NAT from Objects > Policies > Network Address Translation and add the Alias created before. 
 Now on a Policy Rule, under Routing area, change the Rewrite Source address "Use outbound Address" from MASQ to the NAT created before.
