Hi,
How deffie-hellman is helpful here in LAN-to-LAN VPN?
Deffie-Helman is a way to establish secure tunnel between two endpoints.
The Diffie-Hellman group is to establish the strength of the encryption-key-determination algorithm. The security appliance uses this algorithm to derive the encryption and hash keys.
What is the purpose of Hash here and let me know something more about this in concepts of L2L VPN.
During Phase I negotiation in main mode, the ASA uses Diffie-Hellman exchange to generate shared secret keying information, used to generate shared secret keys and to pass nonces-random numbers sent to the other party and then signed and returned to prove their identity.
Transport Mode vs. Tunnel Mode
