Choose an IP range not used anywhere else in your FB config
(and to avoid confusion choose something non-routable ege.g. from 10...)
Set the NAT flag on the ipsec roaming pool definition.
 
'''Think about the NAT'''
 
A problem arises however when the LAN subnet is non-routable (RFC1918 IPs, ege.g. 1923.168.x.x).
In this case the LAN subnet is usually marked NAT in the FB config,
so LAN devices can communicate externally (obviously for outgoing
on the LAN and destined off-LAN).
 
This is overcome, either, by using mapping rules, or by disabling NAT on the LAN subnet and instead enabling NAT on the external internet connection, ege.g. in most cases this would be the PPP connection.
 
==Overview==
*Editing the DNS Service to allow non-local users, we'd recommend using an Allow list that includes the IPsec clients as well as the LAN clients if they are to also use the FireBrick as their DNS resolver. (Setup - General System Services - DNS)
