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.
