vpn with lubuntu 15.10 under kernel 4.3
I'm using strongswan 5.1.2-0ubuntu6.2 in lubuntu-15.10 with kernel 4.3.
Setting up VPN with the NetworkManager, I get no error, BUT VPN does not work.
When establishing VPN manually with: sudo ipsec restart, sudo ipsec up ..., I get the following message in the console:
"received netlink error: invalid argument (22).
Unable to install source route for 139.174.7......"
Howevere, finally it says: "connection "...." established correctly" (however, a VPN connection is not established!!).
This problem does not occur when using the kernel 22.214.171.124 with the same version of strongswan: VPN works okay.
