I'm assuming for packets sent by the gateway. The fragment size is not
negotiated, so the gateway might just default to the minimum datagram
size a host must be able to accept, which is 576 for IPv4.
If it is for packets sent by the client make sure the
charon.fragment_size setting you configured is actually picked up (i.e.
you edited the right file) and it does not get changed by e.g. an
included config file.
