This message does not affect operation of the VPN Client. The issue occurs when Microsoft Outlook is installed but not configured for email, although it is the default mail client. It is caused by a Registry Key that is set when the user installs Outlook. VPN Encapsulation adds to the overall message length. The default MTU adjusted value is for all adapters.
If the default adjustments are not sufficient, you may experience problems sending and receiving data. To avoid fragmented packets, you can change the MTU size, usually to a lower value than the default. Refer to the following table for the specific procedures for each type of connection. The MTU is the largest number of bytes a frame can carry, not counting the frame's header and trailer. A frame is a single unit of transportation on the Data Link Layer.
It consists of header data, plus data that was passed down from the Network Layer, plus sometimes trailer data. An Ethernet frame has an MTU of bytes, but the actual size of the frame can be up to bytes byte header, 4-byte CRC trailer.
Common failure indications include the following:. If you do not experience a problem, do not change the MTU value. Usually, an MTU value of works. Decrement the MaxFrameSize value by 50 or until it works. The following table shows how to set the MTU value for each type of connection. This does not cause any problems and can be ignored. AOL Version 6. AOL Version 7. This requires the use of split tunneling to support the polling mechanism. Without split tunneling, AOL disconnects after a period of time between 5 and 30 minutes.
When making a dialup connection with AOL 7. The AOL dialup process uses a fallback method which, if your initial attempt to connect fails, resorts to a different connection type for the second attempt. When this happens, the VPN Client cannot connect.
This is a known issue, and AOL is investigating the problem. To work around this issue, try to reconnect the dialup connection and try to avoid getting two PPP adapters.
You will need to restart the program. EXE, generated an application error. The result of such errors is that the ZoneAlarm GUI does not run, and therefore a user cannot change any settings in ZoneAlarm Plus or allow new programs to access the Internet.
VPN Client does not support the auto-update package for versions higher than 5. Windows 7 and Vista leave the client hanging while it attempts to disconnect upon awakening after hibernation. To avoid this issue, close the client interface before hibernation and reopen it upon awakening.
Upgrading ZoneAlarm Pro version 3. If the public network matches the private network for example, a public IP address of The same problem can occur if you are using a virtual adapter and the public metric is smaller than the virtual adapter metric.
In Windows 7 and Vista, you can increase the metric of the public network as follows:. Step 2 Right-click the icon representing the public interface and select Properties. Step 4 Click Advanced in the General tab, and set the interface metric to 2 or greater. Step 2 Select the public interface and click properties for the public interface. Step 4 Click Advanced, and set the interface metric to 2 or greater. When a VPN connection is up, data meant for the private network stays local.
For example: In some cases, it is impossible for the VPN Client to make this modification. To work around this problem, make the change manually, using the following procedure:. Step 2 Right-click on the adapter in question and select Properties. Step 4 Click Advanced and increase the number in the "Interface metric" box by 1 it is usually 1, so making it 2 works.
Step 5 Click OK to exit out of all dialogs. Step 6 The VPN connection should now work. There is no limit to the size of the log when logging is enabled. The file will continue to grow in size until logging is disabled or the VPN Client program is closed. The log is still available for viewing until the VPN Client program is re-launched, at which time the display on the log tab and log window are cleared.
The log file remains on the system and a new log file is created when the VPN Client, with logging enabled, is launched. If your certificate has private key protection enabled, every time you use the certificate keys you are either prompted for a password to access the key, or notified with a dialog and asked to click OK.
The prompt displayed when using a certificate with private key protection appears on the Windows Desktop. Refer to 'Known Caveats' on page 17 of this document for the list of known problems. If a VPN 4. A pop-up message appears, allowing you to reconnect the VPN connection. However, selecting reconnect may not re-establish the VPN tunnel. This situation occurred with the VPN 4. The client disconnects after going into any hibernate or standby situations.
This behavior was tracked with the defect ID CSCsf and resolved; however, Cisco cannot guarantee that this solution will work on all hardware platforms and operating systems. If you do see the behavior described in the defect, use the following workaround:. When you awaken your computer, re-establish the Cisco VPN session.
A split-dns value containing wildcards can cause a system failure when a Windows user accesses certain URLs. For example, the split-dns value a,b,c,d,e,f,g,h,i,j,k,l,m,no,p,q,r,s,t,u,v,w,x,y,z can cause a system failure.
To avoid these failures, move the VPN adapter to the top of the binding order list of network adapters.
Note that Split DNS requires entries only for internal domains. You might encounter the following compatibility issues when using the VPN Client with specific applications. Whenever possible, this list describes the circumstances under which an issue might occur and workarounds for potential problems. The following known issues might occur with the indicated Microsoft Windows operating systems and applications software.
Therefore, when using the VPN Client, we do not recommend enabling this feature or running front-end applications that enable it such as Connectify or Virtual Router. The VPN Client does not detect a dialup connection made with Microsoft Connection Manager because of incompatibilities between the requirements of the two applications. If you are having problems, check your network properties and remove the WINS entries if they are not correct for your network.
However, it does not conflict with an installed Token Ring interface. Run Microsoft Outlook and set it as the default mail client. This message does not affect operation of the VPN Client.
