Comment 5 Mohammad Heib 2022-02-16 12:09:56 UTC

Hi @qding,
thank you for reporting this BUG, I think the pluto daemon failed to initiate the connection.
can you please attach the output of the commands below:

# ipsec status 
# ipsec auto --start <connection name you can find it in /etc/ipsec.conf i think it's tun123-1 ) 

thank you so much ad sorry about the previous comment :)

Comment 6 qding 2022-02-22 05:39:43 UTC

Hello Mohamad,

Thank you for investigating the issue and I'm sorry for the late feedback because I have too many tests recently and the machines are not available. There is one important thing that I have to mention that I'm not sure my configurations are correct for OVS NAT-T and I have no idea that if OVS really supports the feature. Just see that with the configurations IPsec tunnel does not work. Please see the log below.
