VOIP ICS/masquerading

some terminal output:

the internet connection is from
<http://usa.asus.com/products/communication/wireless/wl-330g/overview.htm>
into eth0 and a hub is plugged into eth1, then a linksys PAP2
<http://www.linksys.com/products/product.asp?prid=651&scid=38> into the
hub.

firestarter
<http://www.fs-security.com/> is installed, and dhcp, it's just a
matter of configuration, masquerading, I believe.

first, I'd like to "check" the hardware somehow. can the hub be
pinged? alternatively, I have a crossover cable.

again, the internet is WI-FI, I don't have access to the WI-FI router.
the WI-FI adapter plugs into eth0 of the computer and the hub plugs
into eth1 of the computer. I haven't set up masquerading, which, I
believe, is required. again, I have crossover cable to use instead of
the hub, too. the crossover cable could go from eth1 to the PAP2. of
course, the phone plugs into the PAP2.

I've just started to look this recently, but am in a bit of a time
crunch, unfortunately. how do I set up the masquerading, please?


thanks,

ifconfig and route don't show anything from eth1. Have you tried
"ifconfig eth1 up"? If that doesn't work, post the output of lspci.
You can't ping a hub, but you should be able to ping whatever is
connected to it.

Install the ipmasq package, but you need two working interfaces.
