Re: pinging through IPMASQ

[Tony Gettig <tgettig@xxxxxxxxxxxxx>]

You can't ping a device outside your private network if you have network
address translation in use (IPMasq). If I'm not mistaken (and I could be),
you are sending the ICMP packet out, but the server responding to the ping
can't send the reply to your PC behind the NAT. It thinks your IP address
is that of your IPMasq box, so it stops there. I don't think traceroute
(tracert?) or any other util that depends on ICMP will work outside your
private network either. 

In short, you can ping any device on your private network, but not on the
outside, if you are using network address translation (IPMasq).

fine from the gateway box, but for some reason they are not being sent out
if sent from another box on the network.  I'm sure this is something simple
but I'm stumped.
