[plug] rooted routing :(

[bob]

Well I'm obviously missing a piece of the puzzle with regard to routing and 
network segments. Some pointers to where I can find clue sticks would be 
appreciated.

I am transitioning to ADSL (Netcom NB1300+4) from a dialup.

The current setup is

PPP dialup
	|
Gateway/firewall
	eth0(192.168.0.x)
	|
hosts on LAN

Works a treat. 

What I would like to do ( for at least a brief transition period ) is 

PPP dialup
	|
	|	ADSL 
	|	|
	|	eth1 (192.168.1.x)
Gateway/firewall
	eth0 (192.168.0.x)
	|
hosts on LAN

What I can't even get going is 

	ADSL 
	|
	eth1 (192.168.1.x)
Gateway/firewall
	eth0 (192.168.0.x)
	|
hosts on LAN

although I can talk to the ADSL config web server I can't seem to route 
stuff out through eth1. I _thought_ it was as easy as - on the 
Gateway/firewal - del the default gw route (ppp0) add the ADSL box's IP as 
a host route and then add eth1 as the new default gw... apparently not :(.

I had a theory it might have been the iptables fw... nope. I briefly cleared 
it and still no show.

Adding a route to 192.168.1.x to hosts on LAN and setting that as its 
default GW appears to work for a while then fails (is this a problem with 
multiple paths to the ADSL box? ) and does not achieve what I want in any 
case.

Attempts to look back into my network on the ports I have routed on the ADSL 
box to the Gateway/firewall - from spark - gets "Unable to connect to 
remote host: Connection refused". (even with the fw down)

I have tried everything I can think of and read so much I am becoming even 
more confused as to how to proceed - I would very much appreciate some 
assistance in sorting this out.

Thanks.
