Basic Firewall Question

I'm not completely familiar with how ACLs work in conjunction with the firewall, so I have a basic questions whic should answer what I need to know.

Here's the configuration:

Remote Host=====1811 Router=======Internal Server

FE0 is hooked up to ISP Internal network is VLAN1 Internal server is on VLAN1

Internal server has public IP of 1.2.3.4 and internal ip of 10.9.8.7 using static NAT.

How can I block inbound access to a single port (say 1433, for example) originating from a remote host (ie any internet machine) to that internal server and then allow all other traffic?

I'm trying to block a specific set of ports on FE0 but want to allow everything else to flow freely.
