<pre wrap="">Hi,
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.
Kind regards

<pre wrap="">Hi,
Only on the responder.
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.
Kind regards
Noel

<pre wrap="">Hi All,
We want to implement StrongSwan,with IPsec in OpenWRT. IPSec server will be running in CentOS and the OpenWRt router will connect to it using VPN. I have configured the server part, struggling to configure the client part. Do we need to open port 4500 for this first.
Anyone can suggest any solution for this.
