Hi , I am using strongswan 5.9.5 and able to get a tunnel up and working.
two observations: 1. The tunnel Establishment time always changes every 5 min . Is this expected?. 2. I see like continuously isakmp packet with ikev2_init[i] on the one of tunnel end point interface and message like " udp port isakmp unreachable". Is this any error behaviour?. As of now when I run ipsec statusall , it gives output with Security Associations and connection established. Not sure still , why this key exchange is happening?. My understanding of tunnel step is as below , step1: Key exchange step2: Using negotiated key exchange set up a SA. step3: Now on use the negotiated encryption methods to use for traffic exchange. Correct me if i am missing anything here. Thanks in advance RK
