This is a question about my other RH6.2 machine that I
am setting up for IPmasquerading.

This machine is set up with three NICs.  Here is the
rundown:

3c509b (eth1) - Internal network
netgear fa310tx (tulip/eth0) - external network
d-link (ne compat./eth3) - external network testing

IPchains policies set to ACCEPT, no other rules
hosts.allow and hosts.deny have no entries

Scenario:

Ifconfig shows all three devices installed.  Pinging
the internal network works dandy (3c509b).  Pinging
the external network receives one response, then drops
all following packets for both the d-link and the
netgear NICs.  The d-link was used as an external NIC
on another machine for a while and was added to this
one for testing purposes since the netgear kept
failing.  I use a Win98 machine through the same hub
and router pair with no problems.

I have already tried updating the drivers for the
d-link and netgear NICs.  Currently, I am thinking
that the problem lies in one of two places: 1) there
is a problem with the system setup that is
ignoring/blocking the incoming icmp packets (ipchains,
but I turned it off), or 2) my connection is through a
broadband modem that uses DHCP to establish my lease
(I have a static IP, it is just assigned through DHCP
protocol).

Problem 1:

I turned off IPchains and cleared out hosts.allow and
.deny, so there should be no reason to block any
incoming traffic.  Watching the hub lights indicates
that there is traffic incoming, just not being
received by my linux box.  Note that the situation is
the same for a distant host and for pinging the IP of
my broadband modem.  Internal network (192.168.x.x)
pinging works fine.

Problem 2:

I was thinking that DHCP leasing might be the problem
and that the broadband modem just would't recognize my
box since I manually assigned the IP, mask, gateway
and DNS.  I know the information is correct because
they are the same as the values I scavanged from my
Win box when I used it with DHCP.  However, I have
since manually set my IP information on the Win box
and it works just fine!  I double-checked the
information on both machines to make sure they
matched.  You'd think the Win box would have the same
problems.  So...

I'm thoroughly confused.  Does anybody have any ideas
as to what the problem is or how to fix it?

Thanks,
Drew
