Cisco VPN Client Configuration Setup for IOS Router. Remote VPN access is an extremely popular service amongst Cisco routers and ASA Firewalls. The flexibility of having remote access to our corporate network and its resources literally from anywhere in the world, has proven extremely useful and in many cases irreplaceable. All that is required is fast Internet connection and your user credentials to log in all the rest are taken care by your Cisco router or firewall appliance. To initiate the connection, we use the Cisco VPN client, available for Windows operating systems XP, Vista, Windows 7 3. Linux, Mac OS X1. Solaris Ultra. SPARC 3. Cisco VPN Clients are available for download from our Cisco Downloads section. The Cisco VPN also introduces the concept of Split Tunneling. Split tunneling is a feature that allows a remote VPN client access the companys LAN, but at the same time surf the Internet. In this setup, only traffic destined to the companys LAN is sent through the VPN tunnel encrypted while all other traffic Internet is routed normally as it would if the user was not connected to the company VPN. Some companies have a strict policy that does not allow the remote VPN client access the Internet while connected to the company network split tunneling disabled while others allow restricted access to the Internet via the VPN tunnel rare In this case, all traffic is tunnelled through the VPN and theres usually a web proxy that will provide the remote client restricted Internet access.

From all the above, split tunneling is the most common configuration of Cisco VPN configuration today, however for educational purposes, we will be covering all methods. Setting up a Cisco router to accept remote Cisco VPN clients is not an extremely difficult task. Following each step shown in this article will guarantee it will work flawlessly. Below is a typical diagram of a company network providing VPN access to remote users in order to access the companys network resources. The VPN established is an IPSec secure tunnel and all traffic is encrypted using the configured encryption algorithm Engineers and administrators who need to restrict VPN user access to Layer 4 services e. How to Restrict Cisco IOS Router VPN Client to Layer 4 TCP, UDP Services Applying IP, TCP UDP Access Lists article. The Cisco IPSec VPN has two levels of protection as far as credentials concern. The remote client must have valid group authentication credential, followed by valid user credential. The group credentials are entered once and stored in the VPN connection entry, however the user credentials are not stored and requested every time a connection is established We should note that configuring your router to support Point to Point Tunnel Protocol VPN PPTP is an alternative method and covered on our Cisco PPTP Router Configuration article, however PPTP VPN is an older, less secure and less flexible solution. We highly recommend using Cisco IPSec VPN only. In order to configure Cisco IPSec VPN client support, the router must be running at least the Advanced Security IOS otherwise most of the commands that follow will not be available at the CLI promptTo begin, we need to enable the routers aaa model which stands for Authentication, Authorisation and Accounting. AAA provides a method for identifying users who are logged in to a router and have access to servers or other resources. AAA also identifies the level of access that has been granted to each user and monitors user activity to produce accounting information. We enable the aaa new model service followed by X Auth for user authentication and then group authentication network vpngroupml1 R1 configure terminal. R1config aaa new model. R1config aaa authentication login default local. R1config aaa authentication login vpnxauthml1 local. R1config aaa authentication login sslvpn local. R1config aaa authorization network vpngroupml1 local. R1config aaa session id common. When trying to establish an IPSec tunnel, there are two main phase negotiations where the remote client negotiates the security policies and encryption method with the Cisco VPN router. Now we create the user accounts that will be provided to our remote users. Each time they try to connect to our VPN, they will be required to enter this information R1config username adminitrator secret ciscofirewall. R1config username firewallcx secret fir. We next create an Internet Security Association and Key Management Protocol ISAKMP policy for Phase 1 negotiations. In this example, weve create two ISAKMP policies, and configure the encryption encr, authentication method, hash algorithm and set the Diffie Hellman group R1config crypto isakmp policy 1. R1config isakmp encr 3des. R1config isakmp authentication pre share. R1config isakmp group 2. R1config isakmpR1config isakmpcrypto isakmp policy 2. Windows 8 Pro 32 Bits Iso Burner more. R1config isakmp encr 3des. R1config isakmp hash md. R1config isakmp authentication pre share. R1config isakmp group 2. R1config isakmp exit. We now create a group and configure the DNS server and other parameters as required. These parameters are passed down to the client as soon as it successfully authenticates to the group R1config crypto isakmp client configuration group CCLIENT VPNR1config isakmp group key firewall. R1config isakmp group dns 1. R1config isakmp group pool VPN Pool. R1config isakmp group acl 1. R1config isakmp group max users 5. R1config isakmp group exit. R1config ip local pool VPN Pool 1. The above configuration is for the CCLIENT VPN group with a pre share key authentication method configured previously of firewall. Users authenticating to this group will have their DNS set to 1. A maximum of 5 users are allowed to connect simultaneously to this group and will have access to the resources governed by access list 1. Lastly, users authenticating to this group will obtain their IP address from the pool named VPN Pool that provides the range of IP address 1. Creation of the Phase 2 Policy is next. This is for actual data encryption IPSec phase 2 authentication R1config crypto ipsec transform set encrypt method 1 esp 3des esp sha hmac R1cfg crypto transThe transformation named encrypto method 1 is then applied to an IPSec profile named VPN Profile 1 R1config crypto ipsec profile VPN Profile 1. R1ipsec profile set transform set encrypt method 1. Note the encryption and authentication method of our IPSec crypto tunnel as shown by a connected VPN client to the router with the above configuration Now its time to start binding all the above together by creating a virtual template interface that will act as a virtual interface for our incoming VPN clients. Remote VPN clients will obtain an IP address that is part of our internal network see diagram above 1. LAN interface. Setting an interface as an ip unnumbered enables IP processing through it without assigning an explicit IP address, however you must bind it to a physical interface that does have an IP address configured, usually your LAN interface R1config interface Virtual Template. R1config if ip unnumbered Fast. Ethernet. 00. R1config if tunnel mode ipsec ipv. R1config if tunnel protection ipsec profile VPN Profile 1.
