LAN -> VIP (Carp) -> internet not working

[xawiers]

Halo,

I Have pfsense 1.0.1 (Latest stable)

I'm trying to setup VIP using faq and forum messages, but all fails.

Router IP - x.x.x.22
VIP carp - x.x.x.151
LAN IP - 10.y.y.195

in Virtual IPs I add Carp IP address on WAN interface
in NAT 1:1 I add WAN interface x.x.x.151/32 : 10.y.y.195/32

Rules are:
LAN
Allow all from LANnet to any

WAN
Allow ICMP from any to any

I think that this should be enough to have internet from LAN IP computer 10.y.y.195?
I can ping only the internal network and router IP address.

I tried to add rules on WAN:
allow all from any to 10.y.y.195 - no results
allow all from x.x.x.151 to any - no results

on LAN:
allow all from x.x.x.151 to any - no results

Can You point where I could make a mistake?

P.S. all steps I did using faq's and forum messages, I did search before posting message.
Plz point to the answer, not to the search engines.
