Just to make sure everything is working OK. Try setting:<br>
<br>
left=192.168.10.40<br>
right=192.168.10.38<br>
<br>
and <br>
<br>
left=192.168.10.38<br>

Comment out left/rightsubnet configs. They should default to the

Hi Jafar, Peer is also using strongswan 5.3.3. following is

in LAN we want to implement in WAN/Internet. Output of the

<p>Thanks Jafar, for the reply. But after removing subnet
from the config also tunneling failed. Is there any issue
with the version of strongswan 5.3.3. What means
"TS_UNACCEPTABLE notify, no CHILD_SA built"<br>
</p>
</blockquote>
"TS_UNACCEPTABLE notify" means the peer didn't like the
proposed traffic selector. The log shows that your IKE SA is
up, so you don't have a problem there. I can't tell you what
your rightsubnet should be unless you tell us more about the
setup you have. What is your peer running? is it also
strongSwan? <br>
<br>
If you only want to encrypt traffic from 192.168.10.38 to
192.168.10.40 and you don't have other subnets/hosts, you can
switch the connection type to transport mode
("type=trasnport"). Both sides must agree on this. transport
doesn't require left/rightsubnets. <br>

This subnet gets you nothing unless you know that it has
a special meaning in the config that I'm not aware of. You
can have the least significant octet set to zero with a
32-bit netmask. What is the rightsubnet that you are
trying to protect? is it all 192.168.10.0/24? or just one
host like 192.168.10.100?<br>

Check the logs of the remote side.
It means the remote peer did not like the proposed traffic selector. It was probably outside of the network range that its own configuration allows, meaning narrowing failed.

If you use dpd and enforce UDP encapsulation, you do not need to open any ports on the initiator side.
Refer to the UsableExamples wiki page[1] for example configurations that are usable in the real world.
