Re: New to RRAS for Routing

Dear Bill and Robert,

Thank you for your advice. I have set up the Default Gateway according to
your advice. Besides, I have set up RRAS as well.

I believe that I should mention the environment more clearly.

I am setting up a testing LAN and would like to get it connected to Internet
via company's Proxy Server (Address is 192.17.18.111).

On a Windows 2003 Server, there are 2 NICs are installed. For the first one,
IP address (192.17.17.207) is assigned
so that it will connect to my company's LAN with Default Gateway
(192.17.17.50). Subnet Mask for my company is also 255.255.255.0

On the other NIC, I set it up with a static IP address for the testing LAN
(192.18.18.10). Besides, that Server is
set up as a DHCP and DNS Server for the testing LAN. I haven't assigned
Default Gateway for that IP. Subnet mask
for this subnet is also 255.255.255.0

When I setup the RRAS and enable routing, I attempt to type the following
command but it replies that "The route
addition failed: The specified mask value is invalid":
route -p add 192.18.18.0 mask 255.255.255.0 192.17.17.207

In this way, I enter the following and it has no error message. Is it
correct ? Do you have any idea why the mask 255.255.255.0 fails ?
route -p add 192.18.18.0 mask 255.255.255.255 192.17.17.207

For the Internet Connection on the Windows 2003 Server, Proxy Settings I use
192.17.18.111:8080 for Internet Connection.

For the clients in the testing LAN, I find that it can
ping 192.17.17.207 but it fails when I attempt to ping 192.17.17.50, it
fails when I ping 192.17.17.50, not to mention the Proxy Server
192.17.18.111.

Besides, I have attempted to set the Proxy Server for clients in Testing LAN
to 192.17.17.207:80 but it fails. What value should I choose ?

Your advice is sought.
