Firewall/NAT

Hi @ all!

I have a configuration problem with my m0n0:

My mono has an additional DMZ. The IPs of that m0n0 are the following:
WAN: 192.168.10.1
LAN: 192.168.10.x
DMZ: 192.168.9.1

In the DMZ there is a computer with the IP 192.168.9.2. This computer needs a full access to the internet.

The problem is, that regarding some support reasons, an employee needs an access from the internet to this computer (192.168.9.2), but the m0n0 currently blocks all incoming access to the DMZ.
It is not necessary that the DMZ is blocked by the firewall, but if possible, so the support needs only the port 443 (https) and 8899.

I tried everything with Rules, NAT, etc. but without success.

Hope that someone could help me. I have the latest 1.3b12 firmware installed.

Best

No ideas?
Please help - I didn't find a solution since yesterday and tried everyting out. 

Do you have LAN and WAN in the same network???
And a private one on the WAN side too?

Anyway, if thats how it look for some reason, what you need to do to forward a port from WAN to DMZ is to set an inbound NAT rule, which port and which machine its going to, and then check "make a automatic firewall rule" or whatever it says.
Its really simple, you must have messed something up.
