[Ethereal-users] Private IP's - take 2

["Darryl Hoar" <darryl@xxxxxxxxxxxxxxx>]

Well,
thats for the last responses.  I'm still a newbie.

Here is my setup.
I have a machine configured as firewall/nat/router that has two nics.
One nic is connected to my internal LAN.  The other is connected
to my SMC ADSL modem.

My first attempt was to plug my ADSL modem into a spare 3com 3c1611
10/100 hub.  I plugged the firewall/nat/router into another of the ports.
Lastly, I plugged my notebook running ethereal into another port.

I could monitor the packets between the firewall/nat/router and the
ADSL modem.  Unfortunately, I could not see any of the internal 
source ip's (192.168.1.x).

So, I then plugged the ADSL modem back directly into the 
firewall/nat/router nic.  I plugged the hub into the LAN.  Then
connected the firewall/nat/router, notebook running ethereal
into the hub.

Now I can see the internal traffic, but can't see the external bound
traffic.

what am I missing here?  I'm sure its a total newbie thing.

thanks,

Darryl
