1:1 NAT with Firewall

[valamas]

Hi everybody,
I have a /24 public IP range, what I would like to with use 1:1 NAT, the incomeing connections is work but apparently is don't use the firewall rules.
I try to block a port with simple rule in first of the WAN list, but it doesn't work.
It work with separently in and outbound NAT rules,but I don't want to use this, because of the number of settings.

If I look a "whatismyip" site on a PC which own 1:1 NAT-ed Public address, why I look my gateway IP?
[/OFF]

Thanks, Martin

Going to need a much more detailed description of what you have done and what you expect to happen.

Screenshots would probably help.
