Hello everyone. Im here to ask some questions about this topic. I dont really get how L2TP does work.
So in IKE there are two phases to establish an VPN tunnel. Phase 1 (Mainmode/Agressivmode) which builds a managementconnection with ISAKMP (Trades informations like encryption, Key Lifetime,Hash algoryhtmen..)
Phase 2: Data/ payload encryption with IPsec (AH/ ESP). So how exactly does L2TP works together with IPsec? I know that L2TP can tunnel Protocols from higher layers Like IP (Layer 3 Network). But does it use ISAKMP too? And which protocol ist used to encrypt and authenticate via L2TP (without IPsec).
Furthermore here is the standardphrase:" sry for my Bad english.".
