NSA 2400, we have three ISPs (X1, X2, and X3) in failover mode; normally we operate on X2, fail first to X3, then to X1.
Our internal FTP server contacts an external FTP server that only accepts connections from authorized IP addresses, and all three ISP addresses are authorized.
Initially I
had a Routing -> Route Policies set to force all FTP traffic from that server to cross X2, but this won't work if we are in failover mode.
How do I best combine the ISP failover and the FTP connections in such a way that whatever failover state I am in, my FTP traffic goes out the currently active connection? Is it as simple as removing all the NAT and Routing settings? Did I way overthink this at some point in the past?
