when loxilb is enabled and started, enable the
firewall SNAT for green network so green network
could have initiate outgoing traffic like internet
access.
we can achieve this by restoring firewall SNAT setting
from default /var/ipfire/loxilb/FWconfig.txt when loxilb
start up with --config-path=/var/ipfire/loxilb thanks
to the enhancement addressed in issue:
