Good. It's better that way.

This is the one that is used. See your config.sys for details.

Driver vendors tend to distribute sample protocol.ini's. These typically
only have the driver specific section (port, IRQ, etc.)

A couple of comments. setup.cmd contains:

route add default 192.168.1.1 -hopcount 1
route add -net 192.168.1 192.168.1.1 -hopcount 1

The second one is redundant and should be deleted. You are already
sending packets with an otherwise unknown routing to 192.168.1.1

setup.cmd contains:

ifconfig lan0 192.168.1.14 netmask 255.255.255.0 metric 1 mtu 1500 802.3

This looks reasonable.

netstat shows:

Interface 10 Serial Interface dod
physical address 000000000000 MTU 1500

This is owned by Injoy. You might be able to trace it with:

iptrace dod

I don't know for sure.

Interface 11 Serial Interface ppp1
physical address 000000000001 MTU 1524

I have to assume this is set up by Injoy too, but I'm not sure about why
it exists.

Other than the lack of response, the trace looks like what I expect. The
trace appears to be capturing packets as they flow between the eCS machine
and the gateway machine. We are not seeing what Injoy is sending and
receiving over the dial-up connection. For that you can try:

iptrace dod ppp1

and some variants to see what, if anything works. If none of these work,
then try the trace built into Injoy. We really need to see what Injoy is
sending and receiving over the serial interface.

-n is mostly statistics. It says you have 4 interfaces defined:

lan0 - the NIC
lo - the loopback interface
dod - Injoys DOD interface, whatever that is
ppp1 - Injoy's data interface, note the amount of traffic

>Sorry, I would have tried this if I understood the output of netstat -n.

Now you do. Try:

iptrace ppp1

and see if anything interesting gets captured. With luck it will look
like the trace you sent, but with different IP address because NAT did its
job.
