Would you please tell what you're attempting to achieve by the
LAN separation?

If the purpose is to prevent traffic between the LAN sections,
get a third network card. It provides the necessary physical
separation of the subnets.

In principle, you can pick two distinct local networks and
configure the internal network Ethernet card to an address
in each network, using the IP aliasing mechanism. This solution
separates the LANs, if the clients are configured suitably, but
it does not offer any protection against an extra route
or misconfigured IP in the clients.
