Wing Gateway is a high performance failover and load balancer module for Wing FTP Server, it avoids opening unnecessary inbound ports and prevents sensitive data from being stored in the DMZ, and can provide reverse proxy function for all the WingFTP supported protocols - FTP/FTPS/SFTP/HTTP/HTTPS, clients transfer files through Wing Gateway will have the same experience as connecting to WingFTP directly.
Wing Gateway also supports load balancing to distribute incoming connections to multiple FTP servers evenly, let you add or remove WingFTP node dynamically without stopping service. To meet the high availability requirement, you can use "Failover" feature for one server node, then if the running node fails or goes down, the failover node will carry on.
