[strongSwan] help: ping behaviour when tunnel is not established

[Adrian Milanoski]

Have you ran tcpdump dumps along the line and on the both Pub and Priv interface to see where the packets are going? I too am having similar issues with my GW. I see my ESP packets coming in the Pub and then going back out the Pub with its private address when it should be going back out the private network. Do you see similar symptoms?

I request you urgent help in understanding this behavior.

When a connection is configured in /etc/ipsec.conf but the left side of the connection is not responding (say left is unreachable) I see the ping behavior as below

root at ffd-ipsec-189 sanjay]# ping 10.204.74.188

basically ping is stuck or blocked.


Now if I do not have a connection configured in the /etc/ipsec.conf I see that the ping responds like this

root at ffd-ipsec-189 sanjay]# ping 10.204.74.188
PING 10.204.74.188 (10.204.74.188) 56(84) bytes of data.
>From 10.204.74.189 icmp_seq=2 Destination Host Unreachable
>From 10.204.74.189 icmp_seq=3 Destination Host Unreachable
>From 10.204.74.189 icmp_seq=5 Destination Host Unreachable

What settings can be done for a timeout to occurs to that a program that is trying to reach an ip may not be blocked forever if ipsec SA cannot be established ?


My connection setting as follows

#Below Are The Configuration for CCM_CCM IPSec Tunnel
conn LocalIP_LocalIP_10.204.74.188
        left=10.204.74.189
        leftcert=ServLcl.pem
        leftsendcert=yes
        leftupdown=/opt/ipc/security/ipsectunnel/rightdown.sh
        right=10.204.74.188
        rightid=%any
        keyexchange=ikev2
        type=transport
        reauth=no
        dpddelay=5s
        dpdaction=restart
        keyingtries=%forever
        auto=route
