You only need to configure firestarter for eth0, it sounds like you are also configuring it for a bluetooth device. There is a wizard in firestarter, did you use that to set up Linux2?
Also, if I understand your setup correctly, you do not need to set up IP forwarding or NAT on Linux2. The more complicated setup is on Linux1; is it set up OK now?

Is your plan to use Linux1 as your firewall/router and move your Win XP boxes to the subnet connected to eth1? Firestarter should work fine for this, it is how I have my home network configured.


Hey Jeff,

-------------------------------------
internet--->Router----> |eth0(DHCP)----Linux1----eth1 |--------> eth0 Linux2
--------------------------------------
For the external device (usually eth0):

* Enable dynamic IP configuration (DHCP)

The internal device (usually eth1):

* Disable dynamic IP configuration
* IP address: 192.168.2.3
* Netmask: 255.255.255.0

----------#ifconfig-------------

Now Configuring the clients------

If I configure Linux 2 eth0 as DHCP but unable to do, In Linux1 the, even if the status of "dhcpd" running in Linux1. in linux2 i use to get the error of " Determining IP information for eth0 is failed......

If I configure to static IP in Linux 2 the wired connection will establish, but there will be no netwroking, no internet, no ping for 192.168.1.1, 192.168.1.4 etc....

Can you tell me what will be the problem? either i did not configure properly Linux eth1 or is there any other prolem??

Even i started with Firestarter, there is nowhere configure any bluetooth device, but still pan0 is activated, and tried with link "http://www.techotopia.com/index.php/...Linux_Firewall" still no success, I am really apologise for less knowledge on networking, but i need to slove this issue......

Regards

slims.
