a. Choose Status Statistics to display the Tunnel Details tab.
b. What is the Client IP address obtained from the VPN server? Answers will vary but can range from 192.168.2.101 through 192.168.2.150. The pool of addresses was defined in Task 2. Note: Each time you disconnect and reconnect to the VPN server, you receive a new IP address until the limit is reached. c. What is the VPN server address? 10.1.1.2 d. How many packets have been encrypted? Answers will vary e. What is the encryption method being used? 168-bit 3-DES f. What is the authentication being used? HMAC-SHA1 Step 3: Check the Cisco IOS messages on R2 when the tunnel is created. Open the console connection for R2 and locate the message displayed indicating that the virtual interface came up when the VPN Client connection was made.

What is the configuration for Local Area Connection 2? IP Address: 192.168.2.104 answers will vary – 192.168.2.101-.150 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.2.1 R2 Lo0 interface Description: Cisco Systems VPN Adapter Step 5: Test the access from the client with the VPN connection. With the VPN connection from computer PC-A to router R2 activated, open a command prompt on PC-A and ping the PC-C IP address at 192.168.3.3 on the R3 LAN. Are the pings successful? Why or why not? The pings are now successful because PC-A has an IP address 192.168.2.104 in this case that was assigned by the VPN server and is inside the EIGRP domain. PC-A can access the internal PC-C host in the EIGRP network 192.168.3.024 now because it is in the VPN access group associated with the 192.168.2.024 network.

From the PC-A command prompt, telnet to R2 at the Lo0 IP address 192.168.2.1. Log in as admin with the password cisco12345. What is the router command prompt and why? Because the user admin was defined with privilege level 15 the highest, the prompt defaults to privileged EXEC mode R2.b.
