Currently, ASA8.4 VPN test series I: IKEv1 L2L

I have been studying CCNP Security Firewall v1.0 recently. Now the research is complete! It is found that Cisco ASA 8.4 has changed a lot. It is more and more like the checkpoint firewall. The global access control list, whether it is NAT or recently, is exactly the same as that of the cp firewall. After the Firewall v1.0 study is completed, the next research goal is VPN v1.0, which mainly introduces VPN on the ASA. The VPN changes after ASA8.4 are also very large, mainly because of the introduction of IKEv2. IOS15.1T does not seem to be able to be downloaded yet.) IKEv2 is also supported. It can be seen that IKEv2 is an inevitable trend, so I will spend a lot of time studying it recently. Before studying new technologies, it is necessary to know how to configure the traditional IKEv1 VPN in ASA8.4. Next I will introduce the traditional IKEv1 L2LVPN in ASA8.4.(ASA8.4 subsequent VPN trials will be launched soon)
