Comment 1 Sebastian Kricner 2016-02-05 23:07:58 UTC

Also causes problems with IPSec.

INFO: begin Base mode.
ERROR: sendmsg (Permission denied)
ERROR: sendfromto failed
ERROR: phase1 negotiation failed due to send error. a680d720548618fe:0000000000000000
ERROR: failed to begin ipsec sa negotication.

Using racoon.

Comment 2 Sebastian Kricner 2016-02-05 23:08:48 UTC

Kernel 4.0.9 works.

Comment 3 Sebastian Kricner 2016-02-05 23:48:50 UTC

IPSec error is local, had to turn off firewall rules and it does not allow IPSec then.
