One public IP on WAN using NAT.
How to assign two private LAN IP (10.0.0.0/24 and 192.168.0.1/24) on LAN NIC card (same phisical interface)? I know it seems strange but there are some network settings and it's a little hard to change that now, maybe in the future.

Any help please?

would suggest you bite the bullet and get started converting everyone over to the same IP subnet.  there is no way of multi-homing m0n0wall that I know of.

How to assign two private LAN IP (10.0.0.0/24 and 192.168.0.1/24) on LAN NIC card (same phisical interface)?

How about using a vlans?

My monowall provides 26 IPs and DHCP servers on the same interface.
The switch can then distribute these lans to whatever ports I want.

Well, you could always gateway another m0n0wall into your LAN

One would be the main m0n0wall (maybe the 10.0.0.0/24) and the other would sit in front using the 192.168.0.1/24 range that gateways back to the 10.0.0.0/24 range.

I don't know if those two networks are physically separate or not. If they are, it would be easy to keep the legacy IP with just an extra machine.

Otherwise, if cost/time/resources is an issue, I agree, setup a large LAN range and start migrating everyone over to it.

It's possible to hack it into the config, but multiple subnets per broadcast domain is generally considered poor network design. Google ifconfig alias site:m0n0.ch for info.

first time,I come here,view the post,i like.
There are all knowledge,very interesting.
