..., and then do a bind with the source IP from the ssh server on the socket before doing the connect to the server app on OpenSSH client. Then OpenSSH client will be reporting the correct source IP to the server app. Note, adding the feature to "connect_to" would also require editing "channel_connect_by_listen_address" function in channels.c and "client_request_forwarded_tcpip" function in clientloop.c to forward the originating IP I think. I am not an expert at programing or C or posix OSes so my implementation theories and analysis might be faulty.

Hi, Just a usecase that I'm sure has been covered before but just in case its not an openssh solution would be very helpful. I was trying to install software on a server that was firewalled so no outbound http connections would work. I was also tunnelling via another server. Outbound ssh connections also were a convenient option. What would have been nice would be a remote version of
