Hi SS Team,
I am running strongswan 5.0.1, and I can not pass icmp6 traffic with IKEv1.
It creates IKE SA but it fails to create child_SA. The same configurations
works fine with IKEv2,
I have the configuration and log details below for IKEv1 and IKEv2. Please
let me know if this is a bug in strongswan code, and any tips to resolve
the issue.
Here is my deployment:
pc1(2006::2)----(2006::1)strongswan(eth13:2003::2)---(eth13:2003::1)strongswan(2005::1)----(2005::2)pc2
I initiated icmp6 traffic from 2005::2 to 2006::2.
Below is the ipsec statusall output for IKEv1. It fails to create child_sa.

The same deployment works fine with IKEv2. Below is the configuration and
log details with IKEv2. I was able to pass icmp6 traffic from 2005::2 to
2006::2 and vice versa.
