4.26.1 Controlling the visibility of forwarded ports

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:

• The ‘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. (This also applies to dynamic SOCKS forwarding.)
• The ‘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).
