ASA supports two same-security-traffic types. Their application scenarios are1: different interfaces with the same security-level2: traffic between the same interfaces: cisco is called IPSEC hairpinnig, which is mainly defined in ipsec vpn.Description: ipsec vpn is not used for tunneling, or tunneling is not allowed.

Step 1 of Cisco ASA firewall VPN configuration: Create an address pool. To remotely access the client, you need to assign an IP address during logon. Therefore, we also need to create a DHCP address pool for these clients. However, if you have a DHCP server, you can also use a DHCP server.
