While I do not currently have this setup, I'm
asking this question because I keep seeing it posted, and would like to be able
to respond to others...
In a situation wherein there exists a Linux box
connected to a Lan, and that same Linux box's ethernet IP is assigned via DHCP
(i.e. from a BI-DIRECTIONAL cable modem connection) how is Masq configured to
allow other machines to use the Linux box as a masq gateway?
I'm assuming ALL machines and the cable modem
are plugged into a single hub, with only one ethernet interface on the Linux
machine...
the cable modem itself is
also not and "intelligent" device (i.e. it does not have it's own
IP...).
If the first thing ipfwadm does is a "deny all",
doesn't this prevent the linux box itself from sending packets over the
internet?
I'm assuming the eth0 interface becomes the default gateway
for all of the masq'd machines... is this correct?
... and if so is it also the default for the Linux machine
itself? (or isn't this of itself a default...)
Thanks!
