Diferencia entre ikev1 e ikev2 cisco asa

For some reason the ASA shows two bi-directional tunnels up: While the Mikrotik only sees one (it shows each direction as a separate entry After getting nowhere with IKEv2, I went back to basics and tried an IKEv1 tunnel. The same thing happened: both sides showed I have a problem with one of ours VPN Site-to-site tunnel on Cisco ASA 5515-X, can you take a look on this log Actually, i'm sure that pre-shared keys are good becausethe tunnel is working right now!!The tunnel using IKEv1 but even if i enable IKEv2,it's working. Cisco ASA Software running on the following products may be affected by this IKEv1 is a standard method used to arrange secure and authenticated communications. If the Cisco device does not accept any of the parameters the NSX Edge sent in step 1, the Cisco device sends the message with flag NO_PROPOSAL_CHOSEN and ends the Encryption hardware device : Cisco ASA-55xx on-board accelerator (revision 0x0).

• Also supported by native Windows client or even AnyConnect? Then enable IKEv1 on the interface the crypto map will be applied on. The debug commands on the ASA have a slightly different syntax than IOS. The two debugs you will usually find yourself using are debug crypto ikev1 and debug crypto ipsec Settings keyexchange=ikev1 authby=secret ike=aes256-sha-modp1536 esp=aes128-sha-modp1024 rekey=no auto=start reauth=no This is the asa crypto map I was using.

While developing a plugin to test Cisco ASA devices, it was discovered that Based on testing, and the devices Tenable has access to, we believe this will likely impact any Cisco IOS device that supports IKEv2 (and possibly IKEv1) with fragmentation enabled. IKEv2 stands for Internet Key Exchange protocol version 2. The protocol works natively on macOS, iOS, Windows. Several IKEv2 implementations exist for Android, Blackberry and Linux. The key strength of this protocol is resistance to network change This document describes how to configure a redundant site-to-site (LAN-to-LAN) IPSec IKE Version 1 (IKEv1) VPN using Virtual Tunnel Interface (VTI) between two Cisco ASA. ASA VPN module was enhanced with this logical interface in version 9.7(1) and is used to However, a special ipsec ikev1 tunnel does not. It establishes, and stays up, but the client (in this case an Avaya VPN Phone) does not either recieve a client address, or it doesn't ask for one (bit unsure who to blame).
