This section contains additional information regarding compatibility issues when using SoftEther VPN.
11.6.1 Coexistence With Old SoftEther 1.0
SoftEther VPN Server can coexist with Old SoftEther 1.0 Virtual Hubs. However, both programs use port 443 as their listener port so you will need to configure one of them to use a port other than port 443.
11.6.2 Relationship With Mitsubishi Materials Corporation's SoftEther CA
SoftEther VPN was developed from a completely different source tree than that of SoftEther CA 1.x, which is an old version of SoftEther 1.0 that is sold by Mitsubishi Materials Corporation. SoftEther CA 1.x is a completely separate piece of software and as such is not compatible with SoftEther VPN in any way.
SoftEther does not offer any support for SoftEther CA 1.x.
11.6.3 Compatibility With Old SoftEther 1.0 Protocols
Refer to section #11.2.9# for instructions on how to set up SoftEther VPN to be able to receive connection requests from both types of SoftEther 1.0's VPN client software.
11.6.4 Compatibility With Other VPN Products
SoftEther VPN has been designed so that it can be compatible with other VPN products (software or hardware) using the SoftEther VPN protocol that may appear in the future. Therefore, it is likely that if this type of VPN software or hardware does appear in the future it will be able to operate together with SoftEther VPN.
