[Cerowrt-devel] Isn't right with the configuration script

I changed the internal subnet and it looks like everything changes 
correctly but what happens is the interface comes up and I can ping it. 
I see IPv6 traffic coming from it (I believe) but there's no IPv4 
response .I should see if I can set up my Linux machine as IPv6 and see 
if I can access any of the services there. IPv6 is new terrain for me so 
helpful pointers would be quite welcome.

I would also appreciate any pointers to documentation explaining why all 
the little subnets and why so many network interfaces.

My goal in this reconfiguration is to create a /24 subnet and give all 
the interfaces ethernet, Wi-Fi access to the subnet. I'm also going to 
put in a VPN so that outside consultants can have access to the subnet.

I think I can improve the configuration script so that it can "fix" what 
is breaking the IPv4 services and hopefully, increase flexibility. I 
would like to be able to change the entire network configuration for 
different subnet sizes etc. but in order to do that, I will need a much 
better understanding of what the network architecture is supposed to be.

I would also like to fix the configuration script so that you don't need 
to know the starting IP address/network. I should be able to just change 
the desired IP address and rerun the script and have it work. Again, 
with the knowledge, I'm going to put in the effort to make this happen.

For some reason, every time I work on a firewall project, I get stuck 
with IP address management. :-)
