Two networks on the same physical Lan need to communicate

Hello,

I am currently in the situation where I need to communicate between two seperate networks that are on the same physical lan. Some background:

Created a new environment for a small company which has an application and a small number of PC's which now need migrating to the new environment.

The application server and PC's are configured with a different IP subnet to that of the main infrastructure.

Basically the new infrastructure was setup on a new switch with no connectivity to the old environment (as this was not going to be required).

Now the application people want to be able to communicate to both networks at the same time, however we have no router on site to achieve this.

I was thinking of connecting the two switches together and then using static routes to enable the communication between the networks, however am unsure if this is the right way to go.

2: Link the switches and give the PC's that need to be in communication with both networks and IP on both networks (you can give PC's several IP's on several networks on 1 single adapter. Letting them talk to the multiple networks transparantly.

Adding two IP's to the NIC and linking the switches was the solution I went for, only thing is I had to remove the default gateway from the NIC, pretty obvious really but thought I would add in incase anyone else tries the same thing.

Many thanks for the help.
