I have a connection issue with a client - they can telnet (cmd) to port 22 on our public IP and it opens a session.
- they have an internal NAT setup for our public IP for example ins 10.10.10.50 -> dst 22.214.171.124
so when they telnet to 10.10.10.50:22 session opens
when they use winSCP 10.10.10.50 with username/password session fails - the message is authentication error.
Does WinSCP pass the host IP (126.96.36.199) through? So in my clients case, it is passing through 10.10.10.50 in the string?
