Question on TCP MSS with repsect to IPSEC



When we adverstise MSS for TCP connections, am I right in saying that the
MSS value should take into account the ESP and AH header and data.

For example if the MTU is 576, and the AH header+data is 24 bytes and ESP
header +data 20 bytes (assuming 8 bytes padding), then the MSS I announce
should be
(576 - 40 - 24 - 20).

Thanks,
