Firewall/NAT

I have WAN(192.168.200.1/24), LAN0(192.168.3.100/24) and LAN1(192.168.4.100/24) networks with static configuration.
Firewall configuration rules as:
LAN0 network to any.
LAN1 network to any.
WAN TCP 192.168.200.11 any to 192.168.3.11 any.
Problem is that I can’t access any ports from 192.168.200.11 on WAN to 192.168.3.11 on LAN0.
I have no problems to connect from LAN1 192.168.4.11 to LAN0 192.168.3.11.
WAN interface is configured with unchecked (Block private networks) check box.
LOG is:
20:38:44.649564 fxp0 @200:1 p 192.168.200.11,1104 -> 192.168.3.11,3389 PR tcp len 20 48 -S K-S IN
Could you please someone help me. I don’t want to switch to pfsense because monowall is much faster.

I'm not exactly sure what you are trying to do but I think you will either need to set up a NAT rule to go along with your WAN rule or "Enable advanced outbound NAT" to disable NAT altogether.

CS...

uncheck option 'Block private networks' on your WAN Interface. That should do the trick.

Thank you ChainSaw.
Problem is solved.
