When I load ip_vti and ip_tunnel modules, my IPSec connection stops working. uname -a Linux master 3.16.2 #86 SMP PREEMPT Fri Sep 12 22:09:11 CDT 2014 x86_64 Intel(R) Pentium(R) CPU G620 @ 2.60GHz GenuineIntel GNU/Linux - (0:c:/tmp) - - - - - - - - - - - - - - - sudo modprobe ip_vti ip_tunnel - (0:c:/tmp) - - - - - - - - - - - - - - - ping -c 1 -I 192.168.0.11 192.168.1.232 PING 192.168.1.232 (192.168.1.232) from 192.168.0.11 : 56(84) bytes of data. --- 192.168.1.232 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss, time 0ms - (0:c:/tmp) - - - - - - - - - - - - - - - sudo modprobe --force --remove ip_vti ip_tunnel - (0:c:/tmp) - - - - - - - - - - - - - - - ping -c 1 -I 192.168.0.11 192.168.1.232 PING 192.168.1.232 (192.168.1.232) from 192.168.0.11 : 56(84) bytes of data. 64 bytes from 192.168.1.232: icmp_seq=1 ttl=64 time=273 ms --- 192.168.1.232 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 273.347/273.347/273.347/0.000 ms - (0:i:/tmp) - - - - - - - - - - - - - - - Please note that the module was just loaded without any tunnel configuration. I am not sure I am using StrongSwan for IPSec configuration and noticed the same behaviour with libreswan too. Please let me know if I can provide more details.
