Notice that in the EzVPN client configuration, none of the IPSec policies, encryption algorithms, and so forth are configured. EzVPN Client Mode Configuration spoke-ezvpn1-east#Ĭrypto ipsec client ezvpn vpn connect auto group vpngroup key ciscoezvpn local-address Ethernet0 mode client peer 9.1.1.35 username password ezvpn1east The configuration of the EzVPN hardware client is shown in Example 4-3. The client keeps track of the mappings so that it can be forwarded to the correct host on the private network. In Figure 4-2, all traffic from the hosts on the FastEthernet interface on the EzVPN client is translated by NAT to a source IP address of 10.0.68.5, which is assigned by the EzVPN server as an attribute using MODECFG. In this mode, all traffic from the client side uses a single IP address for all hosts on the private network. Automatic configuration- Performed by pushing attributes such as IP address, DNS, WINs, and so on, using MODECFG.įigure 4-2 EzVPN IPSec Client Mode ConnectionĮzVPN Client Mode is also known as Network/Port Address Translation (NAT/PAT) Mode.User authentication- This entails validating user credentials by way of XAUTH.Negotiating tunnel parameters- This is done with encryption algorithms, SA lifetimes, and so on.EzVPN provides the following general functions in order to simplify the configuration process: Minimal configuration is required at the EzVPN client. The tunnel on the EzVPN client can be initiated automatically or manually, or it could be traffic triggered, depending on the configuration or type of EzVPN client used. When an EzVPN client initiates an IPSec tunnel connection, the EzVPN server pushes the IPSec policies and other attributes required to form the IPSec tunnel to the EzVPN client and creates the corresponding IPSec tunnel connection. The Cisco Easy VPN feature, also known as EzVPN, eases IPSec configuration by allowing an almost no-touch configuration of the IPSec client.ĮzVPN uses the Unity client protocol, which allows most IPSec VPN parameters to be defined at an IPSec gateway, which is also the EzVPN server. In a large corporate environment with hundreds of sites, managing the IPSec configuration can get quite tedious. This includes IPSec policies, Diffie-Hellman parameters, encryption algorithms, and so on. My goal is still to get a "regular" Windows 10 VPN to work.As you saw in Chapter 2, "IPSec Overview," for an IPSec tunnel to be established between two peers, there is a significant amount of configuration required on both peers. I used to be able to connect, using Greenbow's client app, to the GroupVPN connection.but something has changed, and I can't get that connection to work anymore. The iOS connection goes through the EasyVPN. Note that I have two VPNs defined, one EasyVPN and one GroupVPN. Suggestions? Other than doing all my VPN work on my iPhone :)?Ĭisco RV325 configuration info. ![]() I wondered if maybe this meant the encryption algorithms specified on the RV325 didn't match what Windows was using.but I don't see any way in Windows to change them. I get a not very helpful error message that "the L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer". ![]() In iOS, the terms "Group Name", "Account" and "Secret" refer to the EasyVPN connection name, the user name I've set up on the RV325 and the pre-shared key.īut in Windows 10 when I enter the pre-shared key in the pre-shared key field, the connection name in the connection name field and the user name in the user id won't connect. I use a pre-shared key.īut I cannot get a VPN connection set up from Windows 10 (latest updated version). I can connect to my home network, which is behind a Cisco RV325 router, from iOS via a VPN without any problem (well, it took a long time to figure out what the various configuration parameters of IPSec were, but after I did it was easy). ![]()
