Firewall/NAT

I have a /29 on the WAN side of a m0n0wall and a private IP range on the LAN side.

x.x.x.0/29

Router LAN:  x.x.x.1/29
Firewall WAN:  x.x.x2/29

I need to direct x.x.x.3 to 192.168.1.122 and x.x.x.4 to 192.168.1.240

Firewall LAN:  192.168.1.1/24

How do I do this?  Even a link to a How To would be great.  I did look but could find nothing.

Thanks,

tss

Add Server NAT addresses for the x.x.x.3 and x.x.x.4 then assign
NAT rules and Firewall rules for the appropriate ports for 192.168.1.122 and 192.168.168.1.240

if 192.168.1.122 was a web server
set something like,

NAT

 WAN  TCP   x.x.x.3  80  192.168.1.122 80

Firewall WAN IFace

 TCP      *         *       192.168.1.122   80
