           Summary: Remote forward: Connect from privileged port if
                    originator connected from privileged port
           Product: Portable OpenSSH
           Version: -current
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P4
         Component: ssh
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: Robert.Dahlem at siemens.com


Got a daemon which checks if connections are originated from a privileged port
(below 1024) to make sure originator has UID==0. Need a way to emulate this when
forwarding ports through secure tunnels.

Implemented ssh option -Q as extension to option -R. With -Q ssh tries to
connect from a port below IPPORT_RESERVED if originator port was below
IPPORT_RESERVED.
