I have a Windows Server 2003 standard installation, which has three network interfaces available (and used).
I want to set up IP routing using RRAS between two of the interfaces, whilst leaving the third unrouted.
I've enabled RRAS and configured it to route between LANs, but how do I isolate the third interface?
The interfaces are configured as follows:
LAN1 192.168.100.0/24 LAN2 192.168.2.0/24 LAN3 172.31.2.0/24
I want interfaces LAN1 & LAN3 to be routed, but for LAN2 to be completely isolated.
