I am trying to set up a cluster of machines that handle outbound file transfers using SFTP and FTP. Given fixed IP whitelisting requirements on the other end of these connections I need all the servers in my cluster to look like the same machine (host/ip address). Anyone know the best way to set this up? Machines are running Windows Server 2008 R2 and Windows Server 2012 R2.
For inbound connections into my environment I have a working solution using a network load balancer (Brocade Virtual Traffic Manager), but for outbound connections however, I am stuck because my load balancer only handles inbound connections. While I am using third party software to originate the SFTP and FTP requests, its essentially SFTP and FTP connections that I am trying to make look like one host/IP to the receiving servers and if I can handle it at the service layer I should be able to get my third party applications to leverage the solution.
This is an enterprise file transfer operations system that has been in place for over a decade so reaching out to all our partners and clients to have them update their firewalls for additional/changed IP address for inbound connections is really a non-starter.
Anyone have any ideas as to how to get this to work? Cant be the first time someone has run into this requirement I would think. Thank you in advance.
