Yes, this ought to work. If it doesn't, I would go back to setup and =
make sure the default 2NIC firewall script is the one you are using =
(save-config and reboot if you're not sure how to apply the changes).=20
Then I would use tcpdump -ni eth0 on the DL box, then try using an =
easily identifiable protocol on the client (web or SSH is easiest). See =
what comes out (if anything) of eth0, and what (if anything) comes back =
in. You could also monitor eth1 the same way.
If nothing comes in to eth1 then something in the client networking =
set-up is wrong, most likely default gateway.=20
If eth1 input looks right, but nothing goes out of eth0, then something =
on the DL box is wrong, most likely routing is not on.=20
If what comes out of eth0 has the original client source address, then =
masquerading is not on or not working for some unknown reason.
If what comes out of eth0 looks right, but nothing comes back in, then =
something is happening on your AP or most likely on the wireless modem. =
Belkin modems (I have one) do have some issues, I believe, with NAT, but =
they've never affected me.
If stuff comes back in to eth0, but doesn't go out of eth1, I don't know =
what could be wrong!
By all means post any of the output from the tcpdump commands if you =
need help interpreting.
I haven't been following this thread in detail, so maybe you already did =
some of these.
