I'm not sure I understand exactly what's going on here. Ok, all
attempts to access addresses
on your LAN (the 192.168.1.* addresses) are being routed to eth1, the NIC
attached to your
ethernet. This part I understand.
"real world" I'm assuming is the address of your provider's network.
(So if your IP was
208.45.67.32, "real world" would be 208.45.67.*) "my real address" then
would be the
real world address with the last number filled in (specifics don't really
matter). So everything
going to your ISP network, is routed through eth0, which, I assume, is the
card attached to your
ISDN/cable modem/modem etc... that connects you to your ISP. Ok, mine is
doing the same
thing.
Now here's the part where I get confused. When you specify a
destination of 0.0.0.0
that seems like a very encompassing "wildcard" address to me. It seems like
you are
routing *all* traffic through eth0, but using your own machine as a
gateway?!? Is this a
default route? Does is override the others or only take access attempts
that are not routed
by the other entries? How can you use your own machine as a gateway to the
internet?
Please excuse me if I'm way off the mark here, but I'm rather new to Linux
and I'm trying to
comprehend exactly what's going on. Thanks again.
