Hi Jafar,
I am not getting any output during "*ip route list table 220*" the
tunnel is established. And it is not allowing any type of traffic any
idea what should be the issue.

Hi Jafar,
Thanks for the information. The ping is stopped as soon as the
tunnel is established to the right IP of the client. I cannot
ping/ssh/http(wget/curl) to the IPsec VPN server. It is the same IP
address where the tunnel terminates.

Hi Sujoy,
Can you ping the the server's IP address that you want to ssh to ?
Is that the same IP address where the tunnel terminates: the
"right" address on the client side ?

Hi Christopher,
Thanks for the response. I want to access the CentOS IPSec server
which is the having tunneling enable from other system through SSH.
In the mean time other OpenWRT client should also be able cur/wget
through the tunnel. Both SSH and http fails while tunnel is
established.
Tried with the following but doesn't works.

Hi Sujoy,
Do you route all traffic through the ipsec tunnel at the moment?
Or is your goal to access the CentOS sever through ipsec?
Cheers,
Christopher

Hi Jafar,
I have successfully establish connection with tunneling
between OpenWRT client and CentOS as StrongSwan server. Now I
am facing one issue. How to enable ssh and http through IPSec
tunnel in StrongSwan.
Thanks

Sujoy,
You have to send me the logs from both ends. It is hard to
know what is the problem with no logs.

Sujoy,
It is really hard to help you if don't give us
full information only sending us one picture at a
time. Please use test files, they are easier to
navigate than screen shots. Your last question
below is a repeat to a question that I answered
before. If you want proper diagnose of the problem
please send the configuration files,logs, routing
table at both ends. see 8 at:
https://wiki.strongswan.org/projects/strongswan/wiki/HelpRequests
Make sure to increase the debug level in your
ipsec.conf files at both ends, something like:
config setup
charondebug="ike 3, net 3, mgr 3, esp 3, chd
3, dmn 3, cfg 3, knl 3"

Hi Jafar,
I am able to establish tunnel when I try to
connect from LAN IP. But with same
configuration(Firewall setting) and same OS
version it failed to establish tunnel with
*nated public IP*.
What means parsed "failed to establish
CHILD_SA, keeping IKE_SA". Please let me know
if you have any idea regarding this issue.
