If you can put the ADSL card in the IpCop Firewall and it has the
drivers. Then you can make ADSL the Red Interface eth0 the Green
interface and eth1 the Orange interface.

I too have a /28 block of addresses.  But use NAT for all internal hosts
whether they are on Green,Blue or Orange.

I then port forward the IP Address/Port combination I want to the
appropriate host.
