[strongSwan] mobile client - per app vpn support

[Tobias Brunner]

Hi Stella,

> - There is no option per-app VPN. Is it correct ?

No, but the next release of the app will support this.

> - There is VPN split tunneling in the IP level. Is it correct?

No, but the next release of the app will support this.

> - What does the following option mean: "block ipv4 traffic not destined

No it will be blocked (basically a route to 0.0.0.0/0 is forced even if
the server narrowed the traffic selector).  So to just treat traffic
that is not destined for the VPN (i.e. does not match the traffic
selector) as if there was no VPN, don't check that box.

Tobias
