How it works: one side of the server network subnet for the 192.168.1.0/24 router for the 100.10.15.1 on the other side of the server for the 192.168.10.0/24 router for 200.20.25.1. Perform the following steps: 1. To determine a preshared key (secret password) (The following example confidential password is assumed to be noip4u) 2. Configure IKE for the SA negotiation process. 3. Configure

restrict the ip address range for access to VTY. Because the number of VTYs is limited, when all VTYs are used up, remote network connections cannot be established. This may be exploited to launch Dos attacks ). Here, attackers do not have to log in. They only need to establish a connection and go to the login prompt to consume all VTYs. A good defense method for such attacks is to use the ip access-class command to restrict the access address of the last VTYs and only open it to a specific man
