[SATLUG] Bridging ADSL to my private network

[jaret at aberlorn.com]

Hi. Thanks for the replies. I apologize for the
confusion b/c I'm learning as I go along here. Let me
try to clarify my thoughts... Thanks, again. :)

Here's a "graphic" of what I want to do...

Internet 
<--> 
{ pppoe(208.x.x.x)/eth0(10.0.0.10) 
    RouterComputer eth1(198.168.1.9) } 
<--> 
{ private network (198.168.1.x }

I have some more questions. 

(1) I used pmfirewall to set up my ipchain
configuration but now Mozilla doesn't connect to the
internet. (even though I have a pppoe connection, when
using ifconfig) Are there some command line tools I can
use to pinpoint what's going wrong (right) here? And
fix it? (Is the presentation Chuck gave at the Aug
SATLug meeting on the internet yet?)

(2) On my private networked computers, what do I use as
the gateway address to connect to the internet? I
assume, it's the ip address of eth1, shown in the
illustration above. 

(3) On my router linux box, how do I tell it to "route"
private network internet requests from eth1 to eth0 and
then get replies?

Thanks, again, for any advice...

1) trying to learn about DNS b/c it's something I'm not
proficient at, new at and it's interesting. I've a good
book by Craig Hunt, called DNS Server Administration,
that I've been experimenting with.

2) Practically speaking, I don't know if I need it.
Maybe someone else can chime in. For my situation, if I
have a company with 50-150 employees, I was looking for
a way to manage the network but not forsaking security. 

Oh, if there is gobbledegook below, I apologize. (can't
wait to get this network setup and using Ximian or like
email client)
