IPMasqing finale
Hi all,
First of all thanks Will for the help. It turned out I had everything set up
correctly and had for quite some time. The problem was a CLOGGED (for want
of a better word) DSL modem. However, it wasn't clogged enough to prevent me
accessing the outside from my Linux box, just the Windows machine. After
power cycling the modem ... Bob's your uncle ... everything worked.
Well almost everything.
I plugged a second machine into the network and gave it the next IP address
in the series
192.168.0.3
however I can't talk to the Linux box. The most I can do is ping the other
masqd machine.
192.168.0.2
Apart from the different IP address, the network settings are exactly the
same as the first Windows machine.
Any ideas?
Cheers
Stephen

<guessing>maybe we should look at the /etc/network/interfaces
file to see if anything is goofy there... my ipmasq worked
out-of-the-box.</guessing> my theory is that the interfaces file
determines how all the connections and default paths work:
# /etc/network/interfaces -- configuration file for ifup(8),
ifdown(8)
# The loopback interface
iface lo inet loopback
iface eth0 inet static
address 192.168.1.1
netmask 255.255.0.0
network 192.168.1.0
broadcast 192.168.1.255
iface eth1 inet static
address ip.addr.shows.here
netmask 255.255.255.0
network ip.addr.shows.0
broadcast ip.addr.shows.255
# where do packets go that aren't gonna be
# locally-determined? to the gateway/router:
gateway ip.addr.of.router
and ifconfig shows--
