If your gateway uses it's public IP as source, then it will not fall
without the net-to-net ipsec policy and go out plaintext. You can
either define a host-host and/or host-net and net-host tunnels to
cover all combinations, or add a left/rightsourceip= pointing to
the internal IP address to change the default src address used
for traffic on the gateways.
