Title:
  strongswan vpn does not work

Status in linux package in Ubuntu:
  Fix Committed
Status in strongswan package in Ubuntu:
  Invalid

Bug description:
  strongswan vpn does not work with any of the published kernels 4.3
  (including 4.3.0-2):

  I have already reported this problem some days ago to strongswan.org under ticket #1189:
  "I'm using strongswan 5.1.2-0ubuntu8 in lubuntu-16.04 (development) with kernel 4.3.

  Setting up VPN with the NetworkManager, I get no error, BUT VPN does
  not work; establishing VPN manually with: sudo ipsec restart, sudo
  ipsec up ..., I get the following in the console:

  received netlink error: invalid argument (22).
  Unable to install source route for 139.174.7......

  But finally it says: "connection "...." established correctly" (as
  when using the NetworkManager VPN connection does not work
  however!!)."

  No such problem occur when using the kernel 4.2.0-19 (also 4.2.0-21)
  instead: VPN works okay.

  The same behaviour is found for lubuntu-15.10 with all kernels 4.3
  where a older version of strongswan is still installed.

  I was told by strongswan.org that this is a kernel bug (a patch
  appears to exist; see the discussion at #1189).
