+An alternative way to forward local connections to remote hosts is
+to use dynamic SOCKS proxying. For this, you will need to select the
+\q{Dynamic} radio button instead of \q{Local}, and then you should
+not enter anything into the \q{Destination} box (it will be
+ignored). This will cause PuTTY to listen on the port you have
+specified, and provide a SOCKS proxy service to any programs which
+connect to that port. So, in particular, you can forward other PuTTY
+connections through it by setting up the Proxy control panel (see
+\k{config-proxy} for details).
