Use the config setting “DynamicForward” Here is a quick example of what it should look like:
Host example.com
User username
DynamicForward 8080
If the DynamicForward option is only given a port number, then it will bind to localhost:port.
You can add a specific IP to get it to bind to an address other than the localhost. Using “*:8080” will bind the proxy to all IP addresses on the box.
To use an IPv6 address enclose the address in square brackets:
[2001:0db8:85a3:0000:0000:8a2e:0370:7334]:8080
For details, please see the ssh_config man page (type man ssh_config).
