I installed m0n0wall in a virtualized environment, I have 10 PCs connected to a router ( 192.168.1.0/24) which connect them to the internet through PPPoE, the problem is that this router does not have a QoS so what I want to do is the following:
Let all the PCs get their IP from the Router and the default gateway will be m0n0wall.
The moon wall will have 2 interface (LAN 192.168.1.20) and (Wan 192.168.1.21 and default gateway 192.168.1.1)
Now when any PC want to access the internet it should go through m0n0wall and then m0n0wall will forward the connection to the default gateway through the wan interface which is the PPPoE running on the router (192.168.1.1)
The big question is this scenario possible or not and what do you suggest?
