Encapsulation of IPsec Datagrams - Performance Question
Although I am still in the processes of studying IPsec, I have yet to find an answer to this question, although I know that it must be in the RFC's. Suppose that I want to encapsulate an IPsec datagram into another IPsec datagram. For example, if I ha
ve a transport mode datagram inside of a tunnel mode datagram. Does the payload data get encrypted twice or only once? In other words, is ESP intelligent enough to determine that it doesn't need to spend CPU cycles encrypting the payload of tunnel mode
if it is already encrypted?
