This is my use case:
I have a bunch of hosts behind load-balancers and clients SSH through the load-balancer. The LB internally creates a new connection so the connection with the end-host has the LB`s IP addres. In order to know who started the request, load-balancer is set up to forward the client IP address in a header. Im not entirely familiar with how the forwarding works, but based on my understanding a magic number is added to the header, followed by the length of the field and then the field itself containing the ClientIP.
Is there a way to tell the SSHD to retrieve the forwarded client IP ? Im sorry if the details are little confusing, im not familiar with the networking part but my team has this use case and would like to know how to have the SSHD retrieve the CIP (client IP) from the TCP packet.
