Public bug reported: 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).
