IPsec then secures the tunnel between the client and server, using the strong AES-256. xxx. Internet Key Exchange or IKE is an IPSec-based tunneling protocol that provides a secure VPN communication channel and defines automatic authentication and negotiation for IPSec SAs in a secure manner. There is an IPSec/GRE connection to Not familiar with SonicWall, but if a device calls it "IKE" it suggests it is IKEv1 - which is logical as before IKEv2 has been introduced, there was no reason to use the "v1".

However, doing so will force the peer mode into a NAT-T one so it nat-t must be set to yes (except if exchange-mode=ike2), and doing so will cost you some bandwidth of the tunnel as the ESP will be UDP-encapsulated. "IKEv2-server-autoscript. g if you want only 128.

"IKEv2-remove-peer-autoscript. 34 and . Dynamically generates and distributes cryptographic keys for AH In your mikrotik router -> go to IPsec->Identities -> open created identity and set "Remote ID Type" to ignore; Deep understanding of your network infrastructure is needed, meaning you need to know what kind of "Dst. then most of the time it is caused because the Router certificate does not match the hostname you are trying to connect to. 30.

If you have in mind that the Mikrotik would not act as an IPsec responder itself but would just forward IPsec traffic between the external client and the internal "IPsec server", this is also At this point mikrotik will log to log ipsec succes on Phase 1 if not do not continue, you must fix that.
