Remote port forwarding

I have the following line in the sshd_config file:
GatewayPorts no
If I launch the ssh client as this:
ssh -l user host -R 9000:otherHost:25
the port forwarding is successful! :-( As you can see, the
'netstat -na' command shows the Secure Shell daemon listening
to the port 9000.
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN
I've checked the code and the only use of the "gateway_ports" variable
is when calling the getaddrinfo function (inside
channel_request_local_forwarding).
The right behaviour should be to deny the port fordwarding request,
shouldn't it?
Any help? BTW, I'm using openssh-2.2.0p1 on Linux (RedHat).
Thanks in advance,
Jose
