If we wanted to tunnel all traffic from the VPN client to our network, we would use the following access-list 120 configuration: R1 (config)# access-list 120 remark == [Cisco VPN Users]==. When the VPN client connects, should we go to the connection's statistics, we would see the 3 networks under the secure routes, indicating all traffic toward these networks is tunnelled through the VPN: It is evident from our last example with the tunneling of our 3 networks, that should our VPN IP address pool be larger, for example 50 IP addresses, then we would have to enter 50 IPs x 3 Networks = 150 lines of code just for the access-list 120, plus another 150 lines for access-list 100 (no NAT)! If SSL VPN is not available then what is the alternate option to provide VPN access to remote users. I'm using subnet 192.168.2.100 for the VPN users.

Once that's done, we need to add a 'no NAT' statement so that traffic exiting the router and heading toward the VPN user is preserved with its private IP address, otherwise packets sent through the tunnel by the router, will be NAT'ed and therefore rejected by the remote VPN Client. !aaa authentication login default localaaa authentication login userauthen1 localaaa authorization network groupauthor1 local!!!! username u1 password u1 ##Khai cc username/pass cho user trn router lun vpdn source-ip 1.1.1.1 < - The IP used for the incoming connections. set transform-set TRSET This screen shows the Easy VPN Group configuration for user 'ezvpn-group1'.

Second-last step is to create one last ISAKMP profile to connect the VPN group with the virtual template: Last step is the creation of our access lists that will control the VPN traffic to be tunnelled, effectively controlling what our VPN users are able to access remotely. As a last note, if it was required the VPN clients to be provided with an IP address range different from that of the internal network (e.g 192.168.50.0/24), then the following minor changes to the configuration would have to be made: This article explained the fundamentals of Cisco's VPN client and features it offers to allow the remote and secure connection of users to their corporate networks from anywhere in the world.
