Routing Problem

[Guest]

I have 2 networks 172.16.7.0 and 192.168.1.0 connected via Win2k3 Server
running RRAS in LAN Routing mode only.

The 172.16.7.0 network has a PIX firewall to provide access to the internet,
it also has server Win2K3 DCs and DNS servers. It also has a Linix Server
(172.16.7.4)

I have installed a Win2K3 Server(DC & DNS) on the 192.168.1.0 network.

Problem is this. I from the Win2k3 server on 192.168.1.0 network I can ping
any Win2K3 Device on the 172.16.7.0 network but cannot ping the PIX firewall
or the linux servers.

I can ping the Win2k3 server on the 192.168.1.0 net fromthe Win2K3 Servers
on 172.16.7.0 but cannot ping it from the pix firewall or the linux server.

I'm baffled.

I configured RRAS for No Authentication.

Help.

To be able to ping machines in the 172.16.7.0 subnet from the
192.168.1.0 subnet, there must be enough routing info on the 172.16.7.0
machines for them to know where the 192.168.1.0 machines are. Without that,
the ping replies will use the default route (which is out to the Internet
via the PIX).

The simplest fix is to add a static route to the PIX to redirect traffic
for 192.168.1.0 to the Windows router. eg

192.168.1.0 255.255.255.0 172.16.7.x

where 172.16.7.x is the IP address of the RRAS router NIC in the
172.16.7 subnet.
