[strongSwan] Missing NAT keep alive packets when forceencaps is set

[Tobias Brunner]

Hi Lars,

Why is that?

> I tried to solve this by forcing UDP encapsulation using forceencaps=yes and expected that NAT keep alive packets also where sent in order to keep the connection alive.

No it's not.  Only if a host is actually behind a NAT (as detected by
NAT-D) are NAT keepalives sent.

No, currently not.
