update Re: [Techtalk] interfacing ppp0 with eth0 ?

[mic]

summary:
-gateway comp is on-line (thanks)
-lan is functioning (right now as we speak i am sshing into the gateway
from a lan comp)
-this lan comp can not get access on-line otherwise

long story:
okay, thanks very much, i am getting there...
removing the self-referencing gateway line did the trick right away.  and
i was able to get the gateway comp on-line using:
-----------------------------------------------------------
-su-2.05b# cat /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
# automatically added when upgrading
auto lo eth0 eth1
iface lo inet loopback

# wan
iface ppp0 inet ppp
        provider dsl-provider

## or is it?, or some other combo such as???:
## wan
# iface eth0 inet ppp
#       provider dsl-provider

# lan
iface eth1 inet static
        address 10.0.0.1
        netmask 255.0.0.0
 --------------------------------------------------------------

i couldn't think of why to give eth0 an ip address, so other than auto, i
ignored it

----------------------------------------------------------------
as i understand it,
-line 1 says that anything destined for the outside world should go
through ppp0
-line 2 says that anything destined for 10.x.x.x should go thru the eth1
and this is the line that i need to add some firewalling on.
-line 3 says that to go anywhere from the lan, use ppp0

so i am not so sure why i am not getting on line from this lan comp, but i
am sure there could still be many reasons.

thanks again.
thanks again,
mic
