 number on the \e{server} (note that most servers will not allow you
 to use port numbers under 1024 for this purpose).
 
+The source port for a forwarded connection usually does not accept
+connections from any machine except the SSH client or server machine
+itself (for local and remote forwardings respectively). There are
+controls in the Tunnels panel to change this:

+\b The \q{Local ports accept connections from other hosts} option
+allows you to set up local-to-remote port forwardings in such a way
+that machines other than your client PC can connect to the forwarded
+port.

+\b The \q{Remote ports do the same} option does the same thing for
+remote-to-local port forwardings (so that machines other than the
+SSH server machine can connect to the forwarded port.) Note that
+this feature is only available in the SSH 2 protocol, and not all
+SSH 2 servers support it (OpenSSH 3.0 does not, for example).
