Is it mandatory to have the incoming and outgoing Security
Association protocol (AH/ESP) and encryption/auth algorithms same?
I went through RFC 2401, though it defines a Security Association,
it is not clear if for a given VPN tunnel, the incoming and outgoing
SAs should use the same protocol ( AH/ESP).
Can you help me?
Thanks & Regards
Yes, both SAs make use of the same security protocol and algorithms.
Look at the definition of an SPD entry for confirmation of this
