Unwound my work stack to carry on with this...had a chance to review the 
docs again and there's one point I'm not sure about.  For clarity, the 
question was about using a Zyxel modem in Bridge mode, which 
automatically disables NAT and how to configure shorewall to take over 
the role.

My router has a "default server" in its NAT setup. NATs everything on 
192.168.1.0/24 but has a default server set as 192.168.1.2. This is 
needed because my internal network runs on another IP block - say 
192.168.8.0/24 - so that only the "DMZ" zone between the router and the 
firewall is 192.168.1.0/24.

I'm thinking that essentially I loose the 192.168.1.0/24 zone because 
what is left of it will be firewall-internal, but I'm not sure, and in 
any case how do I talk to the modem if it's no longer got an IP?

So: if I do need both IP zones, is the old default server setting still 
necessary, and how to I talk to the modem  config if it no longer has an 
IP of its own?

Sorry, rather confused as you can see,
Ruth
