The version matching relationship between SecoClient client and gateway under different operating systems has been verified by full-scale testing, and it is clearly supported.
In actual use, because SecoClient is an independent VPN access software, there is no strong binding relationship with the gateway, so the gateway version other than the above matching relationship may also support docking with SecoClient, and the specific support situation is subject to the actual test and verification results.
Extended data
The basic process of VPN is as follows:
① Protect the host from sending plaintext information to other VPN devices.
②VPN devices decide whether to encrypt data or transmit data directly according to the rules set by the network administrator.
③ For the data to be encrypted, the VPN device encrypts the whole data packet (including the data to be transmitted, the source IP address and the destination IP address), attaches the data signature, and repackages it with a new data header (including security information and some initialization parameters required by the destination VPN device).
(4) transmitting the encapsulated data packet on the public network through the tunnel.
