i dont know about 'self adjustment', but manually you can do it using
the ip tcp adjust-mss (to modify the maximum tcp segment size) and the
ip mtu command, see below:
not for ipsec, but for vpdn based configurations you can use the 'ip
mtu adjust' command
to automatically adjust the mtu for virtual access interfaces, see:
