11.3.2 About the 1/10001000th of a Second Delay Encountered When Communicating Over a VPN
When using SoftEther VPN to perform VPN communication, you may experience a 1/10001000th of a second delay when compared to communicating directly over a physical line. This delay is due to the time it takes to encrypt and encapsulate data (Virtual Ethernet frame) sent over the VPN, and is processing time that is absolutely necessary for the VPN system. However, it will not cause any problems during standard use.

If you are receiving low speed results from your current speed measurement software or throughput measurement service, try the Communication Throughput Measurement Tool that comes with SoftEther VPN or vpncmd's TrafficClient/TrafficServer functions to try and obtain the correct throughput of your VPN. Please refer to section # 4.8 Measuring Effective Throughput# for more information. Be aware that older throughput measurement software can especially give varying results based on the type of line it is testing.

11.3.10 I have more connections to my VPN than I have licenses for. What happened?
In some cases SoftEther VPN Server will allow more simultaneous connections than you have registered simultaneous connection licenses for. This is especially true in a clustered environment. The number of clients connected to the entire cluster is only calculated every few seconds. Therefore, when the cluster controller must decide if it will accept a new connection, it may be using a number (the total number of client connections and bridge connections) that is a few seconds old and thus allow a connection it would otherwise deny.
11.3.11 About MAC Addresses Starting With "00:AE"
All Virtual Hubs have a MAC address that begins with "00:AE". This MAC address is used as the origin of the ARP polling packets sent by Virtual Hubs as described in section #3.4.8#.

If the VPN client computer you installed VPN Client to uses a special PPPoE connection tool (the most common are those distributed by ISPs, but they are not the only kind) to connect to the Internet, the routing table controlled by that software and the routing table controlled by VPN Client may conflict with each other. In this case processes like the one described in section 4.4 Making Connection to VPN Server#4.4.18# may not function properly. If this applies to you, try using a broadband router that supports PPPoE to connect to the Internet instead of the PPPoE connection tool.

As explained in section #3.6Local Bridges#, , using SoftEther VPN to make a local bridge connection between a Virtual Network and a physical network is the quickest and easiest way to set up a VPN. However, you can also use the bridging functionality built into Windows or Linux to connect a Virtual Network and a physical network together into a single segment. However you will need to be using an operating system that supports bridged connections. For Windows, this would be Windows XP Professional or higher, editions of Windows Vista that support bridged connections, or Windows Server 2003 or higher. Even if you use this method you should still set aside a new network adapter for the sole purpose of this bridged connection.

The default MAC address for a Virtual Network Adapter will automatically be determined when it is created. The user can change a Virtual Network Adapter's MAC address to anything they want at any time. Please refer to section 3.4 Virtual Hub Functions#3.4.2# for more information on how to change the necessary settings to do so.
...
VPN Bridge has a single Virtual Hub with the name of "BRIDGE" by default. This Virtual Hub is for defining local bridge connections, configuring cascade connections to VPN Servers, and other VPN bridge software functionality. Therefore, VPN Bridge does not allow the creation of new Virtual Hubs. Please refer to section 5.3 Differences between VPN Server and VPN Bridge#5.3.2# for more information.
...
As explained in section #5#,5. SoftEther VPN Bridge Manual, VPN Bridge can not accept connections from VPN Client like VPN Server can. If you do attempt this type of connection you will receive the message "Not supported".
