openssh unix dev - Aug 2001 - port-forwarding problem!?

Using OpenSSH_2.9p2 on Linux and Sparc Solaris.
Trying to connect from Linux to Solaris, with remote port-forwarding
i.e. On Linux,   ssh -R 3000:Linux:23 Solaris

The connection is established okay, but the port-forwarding does not
work; on Solaris, the connection to localhost port 3000 is accepted, but it 
appears as if no data makes it back to port 23 on Linux. If an older 1.2.30 
sshd is used on Solaris, then things work okay (i.e. the telnet connection 
can be established). Problem happens every time.

Running in debug-mode does not indicate that there are any config-options 
that are denying the forwarding.
