No change in the symptom with 'shorewall clear' on the IPSEC gateway.

But I do notice that the response being emitted by the daemon which is not 
received by the phone (nor even seen in the IPSec gateway interface):
Thu, 2018-03-22 09:51 12[IKE] <3> sending keep alive to 172.56.42.76[49548]
Thu, 2018-03-22 09:51 12[MGR] <3> checkin IKE_SA (unnamed)[3]
Thu, 2018-03-22 09:51 12[MGR] <3> checkin of IKE_SA successful
Thu, 2018-03-22 09:51 04[NET] sending packet: from 192.168.111.16[4500] to 
172.56.42.76[49548]
Thu, 2018-03-22 09:51 01[JOB] next event in 10s 3ms, waiting

... has a -source- of 4500, not a destination of 4500.  I'm not opening this in 
either the IPSec gateway nor the LAN gateway:

IPSec gateway rules:
ACCEPT  $FW     net     udp     500,4500,ipsec,ipsec-nat -

LAN gateway snat
MASQUERADE      10.1.1.30/32,192.168.111.0/24   eth0
rules
ACCEPT          local           net             udp     domain  -
DNAT            net             local:192.168.111.16 udp 500,ipsec-nat-t -      
&eth0

It's UDP so unstateful, so maybe this is -a- problem?  (Aside from the fact 
that the 4500 response doesn't seem to leave the daemon)
