hoe do I enable IP forwarding in win 2003?

[Guest]

I'm in process of implementing new software firewall, and none of my clients
can get on Internet nor external traffic is not forwarded into my web, smtp
servers... everything works fine with old firewall device... I put a call
into support of that software and guy went thru some test with me, and what
he is saying I had hardened OS in some way which now prefens their software
to functional corectly. any way I can ping any of 4 interfaces from firewall
itself, I can ping LAN interface on firewall from client, but I cannot ping
external IP from client even though firewall is stopped at that moment...
assuming firewall is not involved at this point do I have IP forwarding issue
here? how do I enable it?

Really need a better description of your infrastructure here. Best guess:
You are running a 2 NIC Windows 2003 Server and you want client machines to
connect to the Internet through the Server.

1. In order to do this you need to configure Routing and Remote Access.
the wizard will walk you through the process. When you configure NAT
through Routing and Remote Access, you will automatically enable the basic
Firewall - this will conflict with any third party firewall you implement on
the same machine. You can disable the basic Firewall in the RRAS console.

2. If I am wrong in my inference about your configuration, and you simply
want to implement LAN routing on a Windows 2003 machine; you can do this
through the RRAS console - OR edit the registry:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters

Set IPEnableRouter to 1.
