Firewall/NAT

Hi -- apologies if this is asked and answered, but my googling hasn't turned up a solution.

I have a m0n0wall system (using version 1.32 on a Soekris net5501) with a primary LAN subnet of 10.73.0.0/16.  This works just fine.

What I want to do is have the ability to connect devices to the same physical LAN on subnets 192.168.0.0/24, 192.168.1.0/24, and 192.168.2.0/24 and give them connectivity both to the Internet, and to/from devices on the 10.73.0.0 network.  The purpose is simply to make it easier to configure new network widgets that invariably default to an address in the 192.168.x.x space.  I'd like to be able to plug them into any of my ethernet spigots and talk to them from any of the desktops on the main LAN.

I've set up secondary IP addresses on the LAN interface, and tried various firewall and NAT rules, but no joy.  I've sometimes managed to get the 192.x.x.x devices to reach the WAN, but have not been able to get the LAN subnets to route to one another via the m0n0wall device.  Is there a simple way to accomplish this?

Thanks,

John

I'm not sure what you're wanting to do is possible - at least with m0n0wall. It would be easy to have each of those subnets set up on separate NICs, but then they'd each be in a separate broadcast domain, which isn't what you are wanting.
