Pfsense Virtual IPs howto?

Hi Guys
I have been trying to setup a Pfsense gateway, i have a couple of public IPs that i plan to do 1:1 Nat with some servers in my DMZ. I have gone through most threads about VIPs and 1:1 NAT, but i think am yet to get it right.

This is what i did

1. I created the vitual IPs using the Firewall->Virtual IP and ticked the "other" option.
2. I then created a 1:1 of the public IP to a Private IP in the DMZ
3. I then created a firewall rule on the WAN to allow TCP/UDP from ANY to the Address in the DMZ.
4. Also to make my VIPs pingable i created a rule on the WAN to allow ICMP destained for the VIP on the WAN from ANY

it still doesnt seem to be working, i cant even ping, could someone pls guide me through

Thanx lots
