Virtual Interfaces traffic

[yowin]

Hi,

I am testing Zentyal and I´m trying this.

eth0: 192.168.1.1 (LAN)
eth01: 192.168.5.0 (virtual interface)
eth1: WAN

There is a way that both LAN eth0 and eth01 can comunicate each other without restictions, so we can access windows´s shared folders, sql databases, web services, etc in both ways?? I can ping between clients, but the all the other services don´t respond.

Thanks
