What is wrong is the fact that the "path MTU discovery" is broken, so the TCP client cannot reduce the segment size to fit into the available space. MTU size just is, and IPsec transport packets carry some headers and the authentication hash in addition to the encrypted payload packet, and this additional overhead occupies part of the available packet size so there is accordingly less space for the payload. Status of IKE charon daemon (strongSwan 5.9.1, FreeBSD 12.I'd assume there must be something wrong with MTU size.
