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. QUANMA-T (config) # ip local pool vpnpool 192.168.10.100-192.168.10.199 mask 255.255.255.0 Step 2: Create IKE Phase 1.
