Well that takes all the fun out of network discovery against your firewall!

I believe that generally blue is reserved for the Wireless and access
is disabled?

False! See section 2 above - Blue Wireless Zones in IpCop.
You should not need any Ip addresses from Cox.

Please refer to this indepth example of configuring a Blue Wireless zone:

Yes, on a cox network port 80 inbound is restricted. If you do not
have a business account with cox, you are breaking their acceptable
use policy by running "servers" and especially web services or any
inbound packet traffic.
You would need to:
1) Setup a DynDNS to track changes automagically (dyndns.org) give you
a yournet.homelinux.org (or another of a long list of domains, if you
don't have your own) or use dyndns with your own hosted domain.
2) Setup a URL WebHop (free) that points
http://mylamp.homelinux.org
to
http://293.242.2.1:8081 (and works with dyndns so that when cox
refreshes your ip address it is dynamically changed.
3) Port forward 8081 (or whatever port you like) to port 80 on your lamp server.
