Firewall/NAT

Hello,
I'm trying to forward a port to an internal web server and it doesn't seem to be working. Yes, I'm trying to access it from outside my local network... I've had colleagues try it as well from their work/home... no luck at all.

Here is my setup:

Firewall:Rules:WAN
Proto: TCP
Source: *
Dest: 10.11.*.* (internal IP of my web server)
port: 6010 (yes, this is the port the web server is running on)

Firewall:NAT:Inbound
If: WAN
Proto: TCP
Ext. port range: 6010
Nat IP: 10.11.*.* (same as above)
Int. port range: 6010

On the rules page, the first rule is the one that blocks RFC 1918 networks. Is this messing me up? I'm a little confused about that, but from what I can tell, it shouldn't be.

Any help would be much appreciated. Oh, and yes, the web server is running fine when accessed locally with an internal IP

The rules all look OK, either there is a rule that blocks it above this one or it is something to do with the WAN set up?.  How is your WAN set up?  Do you have some kind of DSL router in front of the Mono box?

Thank you. No, the only thing in front of the mono box is my Ambit cable modem. Nothing about my setup is weird at all.

I've figured it out. The gateway entry on the server machine was different from the monowall internal IP. I'm doing it like this because I'm trying out a few different hardware firewalls, and this makes changing their settings as simple as possible. As soon as I changed the server default gateway to the same as the monowall internal ip, it worked just fine!
