I have a SFTP server in DMZ (D-SFTPS) and a SFTP server in LAN (L-SFTPS).  The idea is that any SFTP traffic between WAN and LAN has to go through D-SFTPS and L-SFTPS.  What is the best practice to enable communication between D-SFTPS and L-SFTPS when it only involves sftp between internal server and external server?

Is it possible to share a file system between a server in DMZ and a LAN server?  If so, how?

Golang, also called Go, is an open source programming language that is a statically-typed language with syntax loosely derived from C, adding automatic memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library. Go is a general-purpose systems programming language that aims to be efficient both for development and execution with a focus on fast compilation and increased maintainability of large projects. Go was originally targeted at systems programming tasks such as building server/web applications, high throughput middleware and databases.
