If this is the case, your logs may indicate that exchanges between the client and VPN server are fine well into the IKE main mode security associations.

This issue may also result in no event log messages, if the client's traffic doesn't successfully reach the MX's WAN interface. Note that after creating this key you will need to reboot the machine. SmartByte is one such program known to cause this issue. Disabling the program should resolve the issue and allow the VPN to connect. Sometimes the event log will log the message, " msg: This message will appear for devices that do not have an IPv4 address assigned to them directly, and, as such, are reliant upon an IPv6 transition mechanism like NAT64 to reach the Internet.

Such devices will not be able to connect to our Client VPN solution at this time. If a client is unable to establish a VPN connection, resulting in an error code not discussed in this article, it is recommended to first check for OS-specific documentation about that error.

If the MX is in a Warm Spare configuration, the virtual IP for the uplink will have to be used on the client device for the destination server address. The following sections outline steps to diagnose and fix problems with Client VPN users accessing network resources. At this point it has been verified that the Client VPN session is established and working.

If users are attempting to connect from their own computer, you can't assume anything about the system they're using. This probably sounds silly, but when users tell me that they are having trouble logging in to the VPN, one of the first things I do is verify that they can log in locally. I once had a user complain of VPN problems.

I spent a lot of time trying to troubleshoot the issue. When nothing I tried seemed to make any difference, I decided to double-check the user's account to see whether there were any restrictions on it.

When I did, I noticed that the account was locked out. I unlocked the account and tried again, but it wasn't long before the account was locked again. I reset the user's password and was able to log in without any problems. When I told the user about it, he told me that he'd never been able to log in with that account. When I asked how he got his work done each day, he told me that he always logged in as one of his coworkers.

You can't make this stuff up. Ever since that incident, I always like to verify that the user's account is working properly.

Another thing I like to check is whether affected users are connecting from computers that are behind a NAT firewall. Normally, NAT firewalls aren't a problem. However, some older firewalls don't work properly with VPN connections. Microsoft created the Network Access Protection feature as a way for administrators to protect network resources against remote users whose computers are not configured in a secure manner. One problem I have seen a few times is that Network Access Protection is based on group policy settings.

Therefore, if a user attempts to connect from a computer that is not a domain member, NAP will not work properly. Depending on how the VPN is configured, either the health of the user's computer will be ignored or the user will be denied access to the network. It is also common to configure NAP so that if a user's computer fails the various health checks, a VPN connection is established to an isolated network segment containing only the resources necessary to address the health problem sometimes through automatic remediation.

When this happens, some users may not understand what is going on and may assume that there is a problem with the VPN. If you have a problem and need to call support, uninstall other clients and test before making that call. If you're getting errors in your logs related to preshared keys, you may have mismatched keys on either end of the VPN connection. If this is the case, your logs may indicate that exchanges between the client and VPN server are fine well into the IKE main mode security associations.

Some time after this part of the exchange, logs will indicate a problem with keys. In the preshared key field, enter your preshared key. On a Cisco PIX firewall used in conjunction with the concentrator, use the command isakmp key password address xx. The key used in your concentrator and on your PIX should match exactly. Refer to the client's release notes for more information , Zone Alarm, Symantec, and other Internet security programs for Windows and ipchains or iptables on Linux machines.

In general, if your users open the following ports in their software, you should see a stop to the complaints:. Make sure the ports you configured are also open on the client software. This generally happens as a result of split-tunneling being disabled. While split-tunneling can pose security risks, these risks can be mitigated to a point by having strong, enforced security policies in place and automatically pushed to the client upon connection for example, a policy could require that current antivirus software be installed, or that a firewall be present.

On a PIX, use this command to enable split tunneling:. You should have a corresponding access-list command that defines what will come through the encrypted tunnel and what will be sent out in the clear.

On a Cisco Series VPN Concentrator, you need to tell the device what networks should be included over the encrypted tunnel. This is somewhat specific to these particular operating systems, but could be quite frustrating to troubleshoot! In these cases, traffic that is supposed to be traversing the VPN tunnel stays local, due to the conflict. Right-click the adapter and choose Properties. Now, click the Advanced option, find the Interface Metric option and increase the number in the box by 1.

This effectively tells your computer to use the local adapter second. The VPN adapter will probably have a metric of 1 lower than this new metric , making it the first choice as a traffic destination.

The Cisco VPN client has problems with some older and sometimes newer home routers, usually with specific firmware versions.
