The default settings will listen on all ip addresses and only accept 
connections from a subnet that you are on. You will be able to select 
checkboxes to
1. Listen on all ip addresses vs restrict listening to one ipv6 and one 
ipv4 address as at present
2. Allow traffic from all subnets as at present vs restrict to subnets 
that you have.

To get the current behavior, just uncheck 1 and check 2.

You will be able to use a DNS name or host name in the "IP Address of 
master backend", so you can take advantage of all of the ip addresses on 
your backend if you have DNS capability.
