IPsec questions

[atom]

Hello,

I still have two questions of understanding:

1.)  Why do I always get the following error messages in the IPsec log when using VTI ? I do not get any messages on the remote site.

</snip>

2.)  Why is it that when using Let's Encrypt and IPsec with PSK ( without certificates )
    a) Is the file chain.pem copied from the acme-cacerts directory to the ipsec-cacerts directory ?
    b) Is this certificate sent to the remote peer despite the use of PSK ?

Many greetings,
