Heh.  This is one that's bitten us a fair bit... we were using TCP level
keepalives, but it chews up battery on iPhones.

In the end we compromised by turning off the keepalive for our main

NAT.  The decision about which one to make default was influenced by
a hope that things will converge towards unbroken over time.
