RRAS Router Question

Hello, I have been setting up a Lab in VMware to assist my studies in completing the MCSE 2003.

I have a question about RRAS which I can't seem to get working. I have attached a simple diagram.

There are two networks 10.10.10.0 and 192.168.1.0 that aren't communicating properly through my Windows Server 2K3 RRAS VM. I'm trying to get traffic from 10.10.10.0 to communicate with 192.168.1.0 and vice.

There is an RRAS VM with two network adapters. The server is configured for basic LAN routing.

NIC 1: 10.10.10.1
NIC 2: 192.168.1.1

There are two VMs on the 10.10.10.0 network. Both have NIC 1: 10.10.10.1 on the RRAS VM set as the gateway.

VM 1: 10.10.10.10
VM 2: 10.10.10.20
GW: 10.10.10.1

There are two physical machines on the 192.168.1.0 network. Both have NIC 2: 192.168.1.1 on the RRAS VM set as the gateway.

PC 1: 192.168.1.10
PC 2: 192.168.1.20
GW: 192.168.1.1


The RRAS VM can ping all IPs.

The 10.10.10.0 VM's can ping each other.
The 10.10.10.0 VM's can ping the 10.10.10.1 Gateway.
Interestingly, the 10.10.10.0 VM's can ping the 192.168.1.1 Gateway.
The 10.10.10.0 VM's cannot ping the PC's on the 192.168.1.0 network.

The 192.168.1.1 PC's can ping each other.
The 192.168.1.1 PC's can ping the 192.168.1.1 Gateway.
Interestingly, the 192.168.1.1 PC's can ping the 10.10.10.1 Gateway.
The 192.168.1.1 PC's cannot ping the VM's on the 10.10.10.0 network.

What am I doing wrong?

    Do you have static routes defined?

    I do not have any static routes defined aside from default.

    According to Microsoft Technet Library this is not required because both networks have knowledge of each other.

    Chapter 1 - Introduction to Windows NT Routing with Routing and Remote Access Service

    A Simple LAN-to-LAN Connection

    Figure 1.1 shows a simple configuration with a Windows NT router connecting two LAN segments (Networks A and B). In this configuration, routing protocols are not necessary because the router is connected to all the networks it needs to route packets to.
