Port forward from WAN to WAN?

[rafaurl]

Hi! I'm configuring a pfsense 2.0 box behind an DSL router as follows:

DSL Router
192.168.10.254/24
            |
–---------------------------------
|                                              |
192.168.10.3/24              192.168.10.251/24        192.168.100.1
Web Server                        pfSense WAN =========pfSense LAN

I would like that pfsense forward incoming packets in WAN:8080 to 192.168.10.3:8080 (server in wan subnet). I've been trying something, but can't figure out really how. Is that possible? If so, how? Thanks in advance!

Create the rdr rule and an outbound Nat to force firewall ip onde webserver communication.
