Heh just messing around and checking m0n0 releases I stumbled onto the new forums woooo.....
Anyways, if you have apache running on port 8080, you know that you would need to specify when looking at it in your browser right?
Like for my webserver, I have
http://theneto.com (since you don't need to specify port since 80 is default it would look like this
http://theneto.com:80) <---- Ignore this if you already know.
For example my m0n0wall is on port 8080 so
http://theneto.com:8080 <--- m0n0
http://theneto.com:80 <--- apache
http://theneto.com:3784 <--- ventrilo
etc,etc,etc.
But ya, if you already knew this then maybe the above post is correct... when you add a nat rule you also want it to add a firewall rule too.
check that box,
good luck
